I'm seeing *.register.com down (including ns*) from everywhere. Just a heads-up.
I'll take your word on exhaustively checking every possible address. BTW, do you mean nameservers down, webservers down, or something else? Did the Internet break? *.register.com means nameservers, webservers, whois servers, etc. Of course, Internet does not break, but we've received quite a number of calls about "internet is down" - given that register.com serves a large number of domains, yes, this is operationally affecting.
Would be interesting to see the RFO for that one, including the "why we didn't have any DNS servers offsite
They colo in more than a half-dozen facilities around the world.
or used anycast to at least limit amount of damage".
I also have information from a pretty good source that they actually do quite a bit of anycast. Not that I can see - possibly that depends on a specific domain's webservers.
The glue servers for register.com themselves: Name: ns1.register.com Address: 216.21.234.96 Name: ns2.register.com Address: 216.21.226.96 Name: ns3.register.com Address: 216.21.234.97 Name: ns4.register.com Address: 216.21.226.97 (note just two different /24s) Both of those /24s were down/down about 30 minutes ago, and are flapping/flapping now. route-views.oregon-ix.net>show ip bgp 216.21.234.73 ...

From various vantage points, both /24s are routed exactly the same (7018 in NYC).
