Network problem September 29 (resolved)

In an apparent continuation of last night’s incident, many sites we host were intermittently unavailable between 12:01 PM and 1:20 PM Pacific time today (September 29, 2011). This also caused slow mail delivery and reduced spam filtering effectiveness until around 2:00 PM (no mail was lost, of course).

All systems are operating normally as of 2:15 PM.

This problem was caused by an extremely large-scale network attack against the data center we’re moving from for unrelated reasons.

We sincerely apologize for this incident. We consider it unacceptable, as we know you do.

  3. Can you be more specific about the type of attack? Is it directed at a particular domain/ip address?

    It wasn’t directed at our company or any of our customers. We’re still waiting for a final report, but it took out the entire data center (hundreds of times our size), overwhelming multiple ten-gigabit fiber connections.

  14. The New York Times site was down at that point. Same data center?

  15. Lance,

    Don’t know if they use the same data center (they probably use many), but apparently many data centers are under successful attack today because of a problem discovered in all Cisco Internet routers, leading to lots of engineers scrambling to block it all. Ugh.

  16. Not a huge deal, but as of 8 pm pdt I seem to still be getting a bit more spam than usual (you mentioned that in the op). Everything else is good.

  17. Is it just me?
    It is happening again…
