There’s a lot of buzz right now about a “massive DDoS attack” targeting the US, complete with scary-looking graphs (see Tweet below). While it makes for a good headline in these already dramatic times, it’s not accurate. The reality is far more boring. 1/X
It starts with T-Mobile. They were making some changes to their network configurations today. Unfortunately, it went badly. The result has been for around the last 6 hours a series of cascading failures for their users, impacting both their voice and data networks. 2/X
That caused a lot of T-Mobile users to complain on Twitter and other forums that they weren’t able to reach popular services. Then services like Down Detector scraps Twitter and report those services as being offline. 3/X
So now people are looking around for an explanation and they stumble across sites like the Arbor Networks attack map. It looks terrifying today! Thing is, it always looks terrifying. It’s a marketing gimmick put up to sell DDoS mitigation services so that’s not surprising. 4/X
From @Cloudflare’s vantage point, we can see a number of things that show there is no massive DDoS attack. First, traffic from WARP to supposedly impacted services is normal and has no increase in errors. 5/X
Second, there is no spike in traffic to any of the major Internet Exchanges, which you do see during actual DDoS attacks and definitely would during one allegedly this disruptive. 6/X
Finally, our team know the network operators at nearly all the other major Internet services and platforms and none of them are reporting anything anomalous. 7/X
Except T-Mobile, which is having a bad day almost certainly entirely of their own team’s making. So, please, #hugops. And don’t worry, this is one thing that does not need to get added to the list of craziness that has been 2020. 8/8
Like look this man is the clear expert in this field and has sources as well....yet shit was fucked up way beyond tmobile. Idk I'm not in that field with any experience but I just don't buy this
My bad! Didn't mean no disrespect to the lil green guys 👽👽 They can surely end us same as the Murder Hornets. It's just hard keeping up with all the apocalypt-y breaking news stories...
Seems coincidental that other services experienced issues today, including one of the largest enterprise cloud telco providers. That's not T-Mobile related, but is either same cause (Tier 1 backbone), or coincidence?
EVERYTHING IS FINE
DONT WORRY
CHINA / EU and the rest of the world are attacking the United States, but this rich nerd isn't affected, so just calm down and forget about it.
Thank you immensely for explaining what happened, in terminology that ordinary folk can understand. That is not a small thing.
You and @hacks4pancakes talking sense 24/7/365 in spite of it all.
I live in MI, last night our Comcast Xfinity internet service went down at same time my sons Verizon cell phone service also crashed. I still had use of my Xfinity cell service however.
I believe it’s either a Tier 1 provider such as CenturyLink or Layer 3 having an outage but I would assume other carriers would also see issues, but on the other hand, a leaked internal T-Mobile document stated that they would be moving over 1mil Sprint customers to their network
Exactly. Cell service uses existing fiber optics and other companies to route cell traffic. It is a routing issue. It's not disputed T-Mobile may be having most of the issues. My point is that ATT and Verizon like to deny the problems even if their users are having issues.
Can you please explain what these graphics represent? There isn't a title on the graphs or titles on the axies. They kind of seem BS without a concise explanation.
You guys are cloudflare, which cellular provider uses your service? I don't think anyone does so why do you think your Cloudflare graphs matter? Of course you don't see traffic, it doesn't even go through you guys...
Would there ever be an instance where hiding the fact a massive attack hit us would be deemed the best route to take to avoid an escalation?
Kinda like how we lied about any injuries in the Iran rocket attacks so that we didn't have to go to war?
Nation states participate in covert cyberwarfare on a daily basis. Russia interfered in the U.S. election, a Chinese APT group was responsible for the Equifax hack, etc. I think the only difference here (if was a legit attack) is a lack of subtly.
Thank you for clarifying. I have seen a graph that was from yesterday and the Down detector today though it appears that the outages have passed for the most part.
^^^ exactly.
Companies firing people who break things damage themselves in three ways.
i. They invariably wrap themselves in "feel-good" change control which adds nothing but ass-covering.
ii. It destroys any and all innovation.
iii. The person you fired probably fixed it too.
Systems are complicated. People make mistakes. Easier to learn from them if they’re still around to tell the war stories. Firing someone for an honorable mistake is huge mistake.
Ahh.. the armchair sysadmins are always great fun.
I especially loved them after an S3 outage postmortem a while back after an operator fat fingered a command.
As if any of them could run something on that scale/criticality 🤣
It’s exactly that. Find the intention. If the intention was honourable find out what went wrong and how to avoid it in future, so everybody learns. Learning is good. Throwing sacrifices into a volcano to appease the gods, less so.
My senior sysadmin in my first admin job told me: you're gonna fuck up sometimes. Fess up and get help asap to fix it, document it, learn from it, and I'll have your back if management gets angry. Sure enough, it happened, we fixed it quickly, and life moved on.
Cellular networks are reporting issues connecting to 9-1-1. If you have an emergency and you can’t get through on a cell phone, use text to 9-1-1 or call 720-913-2000 and press 1 for assistance. @DenverPolice@Denver_Fire@DHParamedics
Good to know, I'm sure all the websites you host and disguise on Cloudflare are safe with their Libelous Posts, #Racist Posts and Vulgarity. Shame my friends still have to suffer while you wash your hands : Cloudflare enables Criminals #BlackLivesMatter#LGBTQ
That's not how Dunning — Kruger effect works. It isn't even that pronounced. It says nothing about experience over time.
In fact, the original paper says the exact opposite: the more confident a person appears, the more knowledgeable they are.
in the psychology field it is widely accepted that people who know almost nothing have high confidence according to the dunning-kruger effect. all graphs you find when you look it up show the same exact thing more or less.
Do you also think vaccines cause autism, and tainted water can make frogs gay?
If you do, buy some of my merch. If you're dumb enough to make that comment, you're also dumb enough to spend your money on a creator you've never heard of.
They appeared to have made some changes in routes without a proper blackout plan if things should go wrong. It isn't the first time this has happened. It takes me upwards of 2 hours to write up a proper blackout plan for network changes. This is sad.
Who is this 12 year old? He didn't go to law school.
He doesn't look old enough to have gone to HIGH school?

Speed isn't everything, though. It's still 5G.
Both Verizon and T-Mobile have real 5G, with real benefits.
And there's a pretty obvious reason why smaller countries have the fastest LTE speeds.
Or maybe, just maybe, considering that TMobile and Sprint are in the middle of combining their networks and rolling out major updates to both networks to make everything work cohesively, something went wrong. But please, explain to us all how this is obviously 5G's fault 🙄
T-mobile leading the what? Lmfao dude, why does every alarm artist come out the woodworks with the inanities as if on cue?
...T-mobile leads the pack on 5g 🤣
As someone with a just-above-layman's understanding of the Internet, may the deity of your choice bless you for breaking stuff like this down. I rely entirely on patient experts.
Was unable to send and receive text messages today--and therefore unable to log in to work on my QuickBooks account. We have T-Mobile. It's a big deal to me. Lost a day of work.
It can, not always depending on where the fault is but most ISPs have multiple local/state servers, major data centres, etc between you and the wider internet so unless the fault is higher up the ladder you can easily be fine while on the far side of the country.
So a configuration change at a cell phone company brought down the entire world's internet? Gee that's concerning don't you think?
I don't believe you.
T-Mobile did have a major network change planned for today, and it only takes one major ISP to go down for everyone else to be impacted.
Look at the trends, it's clearly not a DDOS.
If I'm not wrong, one of highest DDoS attack had the target at Github, with the peak close to 1Tbps.
That is one rease why every ISP should be part of #MANRS and do they homework.
Its not so simply to knock down a huge server like Facebook that has a lot of CDN around the world, but it cause some momentaneous slow down and depending, can make some difficult to some % of users to reach they service
I may have less but the websites don't show anything different. Why is the United States showing the most rn?
threatmap.fortiguard.comdigitalattackmap.com
People are even saying their Verizon service went down, can't call 911, people are getting emergency alerts on their phone
I'm saying if someone with less than 100 followers is going to tell me that these websites don't show any status of a DDoS attack, I have to wear a cap.
You validate someone’s opinion on how many followers they have? Not, I don’t know, their experience in a field? He is right. That’s a boring day in the office.
It really is, though the impact on FB messenger of whatever the hell was going on actually going on today affected me and my partner (different countries currently) on and off for a bit.
Dug up fiber line, routing hardware failure, expired security certificate, leased bandwidth from an affected network operator? Why don't you ask them instead of doing whatever this is?
So you want Cloudflare and Rachel Maddow to investigate a local internet outage that lasted less than 24 hours where less than 0.008% of the US was affected?
Counter? This too

DDoS traffic doesn't require GB's of data, specifically crafted traffic can also put a server on it's knees.
Do you also think UFOs make crop circles, and psychics are legit?
If you do, buy some of my merch. If you're dumb enough to make that comment, you're also dumb enough to spend your money on a creator you've never heard of.
I don’t believe ANYTHING anymore especially news via Twitter since it’s all censored to fit a narrative of them evil elites like Hillary. They are fendangling the network with more surveillance AI technology
Do you also think vampires are real, and 9-11 was an inside job?
If you do, buy some of my merch. If you're dumb enough to make that comment, you're also dumb enough to spend your money on a creator you've never heard of.
Thank you very much for making clear that we are not under a DDoS attack and that a true DDoS of the scale some claimed we had would have made it impossible for you to even send what you typed.
Definitely shared infrastructure... you only see the difference on the edge because that's how Verizon or T-Mobile broadcasts it; on their frequency and technology.
You do have to understand that a DDoS doesn't need to use gigabytes of internet traffic. If someone knows how to attack a server to make it take time to process a lot by just using a kb of data, then so be it.
Pretty sure a major DDoS attack would be amazing for us given we’re one of the only companies that could stop it.
Good lesson: when you hear hoof beats, think 🐎 not 🦓.
Is it right that this is called a bgp attack not a ddos attack as it’s a dns hijacking thing not an overload of packet request and there are news that it’s still under control and not considered a real attack yet!?
Are there not other forms of attacks other than DDOS that could have caused the outages that people experienced on twitch and other services?
What other types of disruption attacks or accidents could it be?
Feels like we're pretending the other outages just didn't happen...
Thank for your excellent explanation of the T-Mobile outage. I really appreciate you sharing your and your team's knowledge of the underlying issue, how people reacted, how the rumors began, where bad actors added bad info and then how it spread across social media. THANK YOU!
Comcast goes down every so often .... too bad it’s not permanent so we don’t have to pay these exorbitant bill amounts every month .... a total racket !!! #comcastrippoff
I don't tech, just parroting what I've heard which is attack BGP attack on Level 3 which caused downstream problems. But that BGP vulnerabilities usually only take an hour to fix, so that was maybe a separate issue.
Stop parroting what you heard without evidence, that is the entire reason this stupid DDoS nonsense took off in the first place, and is the entire reason Social Media is a toxic wasteland of misinformation
Dont downplay what happened today. A town in Tennessee had to shut down their entire computer grid cause of ransomware. Alabama paid $300k to get their systems back up. Chinese group APT Gallium shutdown Australia's #1 cell provider A1 Telekom, BellTroX infiltrated high officials
And much more. DDoS attacks are used to shield the actual agenda. Look at this list of companies who were all affected just today. This never happens they are searching for our power grid and comms. DO NOT LISTEN TO ANYONE WHO DOWNPLAYS THIS.
You use a DDoS attack as a smoke screen so that you can remain persistent and undetected on compromised systems/networks, not to carry out ransomware attacks that are the opposite of covert by nature. I have absolutely no idea what correlation you are drawing there.
And A1 is an Austrian Telecom, not Australian. And that has nothing to do with today because they compromised in late 2019 and only just recently stated they had fully remediate the network.
I do definitely think that it leaks past just T-Mobile however. The weird stuff I saw at work today on some of our customer's systems makes me think that something is up with routing somewhere. Not only are some of our SIP trunks riding out on Intelliquent are a bit higher (1/?)
...ping than normal, and one of our Centurylink PRIs has stopped calling Google Voice numbers along with most T-Mobile and AT&T numbers at times too. The PRI is a bit of a mystery but the SIP trunk latency is significant of something past T-Mobile. (2/2)
and that does NOT MEAN A DDoS attack. That could be just routing issues thanks to a misconfigration on T-Mobile's side causing a flood of traffic. (3/2)
