DNS servers of a major internet provider in the Czech Republic are down now. Probably not a coincidence (other DNS server's stats show increased traffic so my guess is that Vodafone's DNS servers were unable to cope with the increased traffic and crashed https://twitter.com/BlazejKrajnak/status/1445063232486531099).

It's crazy that half the country doesn't have internet because Facebook stopped working.

Facebook is likely scrambling private jets as we speak to get the right people to the right places.

this is not new, this is everyday life with helping hands, on duty engineers, l2-l3 levels telling people with physical access which commands to run etc. etc. etc.

Is anyone else seeing knock-on effects at the other major public DNS providers? I'm seeing nslookups sent to 4.2.2.2 and 8.8.8.8 intermittently timeout if the hostname does not belong to a major website. CloudFlare DNS (1.1.1.1) doesn't appear to be impacted. For example: [root@app ~]# nslookup downforeveryoneorjustme.com 4.2.2.2 ;; connection timed out; trying next origin ;; connection timed out; no servers could be…

No idea if it’s related but a lot of Tor websites have also been offline all day (BBC, ProtonMail etc).

Discord [1] is taking a toll from the increased traffic as well:

"We're noticing an elevated level of usage for the time of day and are currently monitoring the performance of our systems. We do not anticipate this resulting in any impact to the service.

We have temporarily disabled typing notifications. We expect these to be re-enabled soon."

I like how FB decided to send "ramenporn" as their spokesperson.

I'm worried about that person. I doubt Facebook will look kindly on breaking incident news being shared on reddit.

lol no one cares. we're all laughing about this too (all of us except the networks people at least...)

It shouldn't be too stressful. Well-managed companies blame processes rather than people, and have systems set up to communicate rapidly when large-scale events occur. It can be sort of exciting, but it's not like there is one person typing at a keyboard with a hundred managers breathing down their neck. These resolutions are collaborative, shared efforts.

"it's not like there is one person typing at a keyboard with a hundred managers breathing down their neck. These resolutions are collaborative, shared efforts" Well, you'd be surprised about how one person can bring everything down and/or save the day at Facebook, Cloudflare, Google, Gitlab, etc. Most people are observers/cheerleaders when there is an incident.

> Most people are observers/cheerleaders when there is an incident.

Yeah, a typical fight/flight response.
