"Large cloud providers are very competent and never go down", episode over9000.

Seems like FB's authoritative nameservers are down, and long enough for DNS caches to start expiring:


If anyone is wondering, it's not getting any better. Snapchat, AWS, Twitter, several major mobile providers (T-Mobile, AT&T, Verizon) joined the "seems down" club.


The Verge has the scoop:

> Cloudflare senior vice president Dane Knoecht notes that Facebook’s border gateway protocol routes — BGP helps networks pick the best path to deliver internet traffic — have been “withdrawn from the internet."

CloudFlare blog as a good write-up:

(reminder, CloudFlare is part of the problem, not of the solution)

@rysiek I know it's wishful thinking, but I hope the screwup of this magnitude will makes some people realize they don't really need facebook.

@avolkov @rysiek or at least that they can't afford to bet it all on FB... as many currently do. Poor fools.

@rysiek That "we got 30 times the DNS queries for Facebook domains because everyone and everything was excessively retrying" graph is 🙄

@galaxis now think what this does to any other DNS recursive resolver operator.


The conclusion in their article is a good proof of your remark:

> Today's events are a gentle reminder that the Internet is a very complex and interdependent system of millions of systems and protocols working together. That trust, standardization, and cooperation between entities are at the center of making it work for almost five billion active users worldwide.

While the problem in this case is clearly centralization, which they refrain from saying.

@rysiek i heard this might be Azure related from coworkers FYI, haven't validated that yet
