Tony BarkWidespread Cloudflare outage blamed on mysterious traffic spike
Treczoks
VieuxQuebIt was actually the system Cloudflare uses to catch and block bots that went haywire.
They had a fake database you could query that would pull content from a bunch of different shard databases. They updated the config so that systems querying it could see the shards in addition to the main dummy DB. The tool that pulled data out of it assumed that it could only see the dummy, however, so it just asked for everything when it pulled a report to pass to the filtering system.
The filtering system assumed the report it received would be properly formed and crashed if it got one that was malformed.
melroyI hope more websites will move away from cloudflare. I could not access 90% of the web anymore. This is insane if just 1 company goes down, the whole internet is dead. The internet is broken!
and itâs fucking annoying to check the box to âprove youâre a humanâ when trying to access almost any site. some days it will make me do it three times before letting me through
I understand the need for anti-bot or DDoS protection, but there are better and free options today. Like Anubis. So please, in the love of The Internet, move away from cloudflare. Ideally yesterday already.
altkey (he\him)Anubis never worked for me on mobile. Iâm afraid of mass adoption if that wonât be fixed.
XylightâźAnubis isnât even comparable to cloudflare. The reason cloudflare is so effective is that they can oversee which IPs are spamming or being abusive to certain websites, and can throw up protections quickly.
Anubis is just a prompt that wastes CPU cycles and tries to make it more expensive for AI crawlers to do so (since they care a lot about compute costs, of course)
next time youâre at bat against one of these, you may try moving less diligently / efficiently to the checkbox. overall, a slowed and less exact approach. Iâve not tested this enough to REALLY say it makes a difference, but in cases where I continually fail, going slower does seem to be the time I finally get through.
I find the same for the picture puzzles where you select images that match or apply to the posted context or whatever else the mission may be.
He still doesnât know, guys đ
DreamButtInternet is so fucked up and manipulated that people would be better without it.
Itâs very normal for countries to DDOS each other to test their limits, and if it could be incorporated in an attack.
And yes, of course the US is also testing this against other nations.
TomMaszEvery DDoS that hits Cloudflare is bigger than the previous one. Thereâs bound to be one that they couldnât instantly mitigate.
Did Akamai, their competitor, ever blinked? (I donât remember).
Even if they did, the importance of decentralising the internet away from a few big providers is no joke.
Yes of course I totally agree.
This was a malfunction, not a DDoS attack.

Arenât spikes in unusual traffic the exact thing Cloudflare itâs supposed to protect you from?
Task failed successfully.
BeatTakeshiFission Mailed
They protected the endpoints. They just werenât able to route traffic to them.
From a Cloudflare customerâs point of view, I donât care if my site is down from a DDOS or a Cloudflare outage, but the latter seems to happen more often.
From another cloudflare customer, if our sites still work internally itâs marginally better than them being broken both inside and outside the org as they would be if they were ddosed directly. I guess it depends on what kind of services youâre running.
As it stands? Cloudflare is still incredibly effective at protecting customers from those DDOS attacks. Which, depending on your hosting solution, can mean very noticeable monetary savings because YOUR hardware/connection didnât spike. And, regardless, can mean noticeable monetary savings as your engineers didnât need to recover a crashed system because your setup was just sitting there idle.
That said: If you truly need high availability? You need to do what downdetector did and have alternatives ready in the event that Cloudflare falls over. Same as with your ISP⊠which should be ISPs plural.
Yeah, but just one âunusual spike in trafficâ - so it seems. /s
Buying a car is pretty capitalist.
Iâm not envious and I like the thought of some places on the planet having it normal for one family to have few cars, but - in certain places where capitalism has already been disrupted a few times in history, like Moscow, Russia where I, eh, reside, am headquartered, dwell, roam, ⊠- and those places are richer than much of the world, - people would think the guy from the screenshot doesnât have many reasons to try disrupting it.
NatakuNoxAmazon is now saving Americans from the crippling debt most of them seem to get into to drive a shiny box⊠I wasnât expecting that.
JohnnyCanuckMy bad, I started downloading The Lord of the Rings movies - Extended Edition. Sorry!
How many times have I told you not to download movies or games in the middle of the day? Youâll tie up the phone lines.
cyranoYou tell weâre all old as fuck Millennials, because nobody else would make this joke. Lol.
I canât even explain dial up modems to my son because Iâd have to start by explaining what phone lines are.
I had a Gen Z person ask me how I got a â3D printer save buttonâ when I had a floppy disk for some reason.
ace_garpI think thatâs a big part of why I like lemmy.
There are plenty of tech-savvy critical thinkers in the younger generations, but the naïveté, tech illiteracy, and lack of critical thinking ability of the average internet commenter / poster is appalling.
Iâve seen it just get worse and worse.
The internalized self censorship, the laissez faire attitude towards digital privacy, just pure fucking idiocy.
Wake me up when September ends.
Sorry friend, it is Eternal.
Kilgore TroutI am 26 and this is my childhood too.
No longer relevant pro tip - an extra pair was typically left at the incoming service, which was used for testing. It worked as a second line and didnât interupt the main pair, allowing for a functionally free second phone line (that didnt have incoming service).
Perfect for modem use!
Ten movies streaming across that, that Internet, and what happens to your own personal Internet? I just the other day got⊠an Internet was sent by my staff at 10 oâclock in the morning on Friday. I got it yesterday. Why? Because it got tangled up with all these things going on the Internet commercially. They want to deliver vast amounts of information over the Internet. And again, the Internet is not something that you just dump something on. Itâs not a big truck. Itâs a series of tubes. And if you donât understand, those tubes can be filled and if they are filled, when you put your message in, it gets in line and itâs going to be delayed by anyone that puts into that tube enormous amounts of material, enormous amounts of material.
Lies, the internet isnât tubes, itâs a small box
Dharma Curious (he/him)I had fully forgotten the phrase âyouâll tie up the phone line!â And I just had a nam style flashback of sneaking internet time during the day when my mom was at work, and praying that no one tried to call
devfuuuDid I miss something? Is everyone downloading the Epstein files today?
Soviets?
