Brief high load on web12 server June 6, 2013 (resolved)
Beginning at 10:38 AM, the “web12” server experienced high load that made sites on that server slow (or intermittently return “503 errors”) for several minutes. The cause of this problem (a user running a process that caused extremely high disk usage) has been identified and resolved.
We sincerely apologize for the inconvenience this problem caused.
