Hi all,
Posting a belated update on this. Clearly we sorted out the Akismet issues some time ago. During the last week since this happened we've been working hard to upgrade our systems and that upgrade is now almost complete. The plugin scanning portion of our infrastructure has been upgraded to a brand new beefy distributed storage system with 8 additional CPU cores thrown in to speed up plugin hashing. That was the biggest task. Did you know that as of right this minute WordPress has 42054 plugins in the official repository comprising over 350 gigabytes of data?
We're busy completing the migration of our theme and core mirrors to the new system and that will be done within 48 hours. However, this is not critical because we haven't had any performance issues in those areas. There also won't be any down-time as we complete this task.
So as of right now all systems are green and have been since we resolved the original issue just under a week ago.
Regards,
Mark.
