During planned network maintenance this evening, an error by our team cut off traffic to a large subset of your custom domain blogs. Painfully, the full recovery took 1¾ hours to complete.
This is obviously unacceptable and an enormous disappointment to everyone working to keep your blogs fast and stable.
Ironically — or absurdly — this maintenance was part of ongoing infrastructure overhauls that have already done a tremendous amount to rid Tumblr of the awful tumblebeasts. We’re heartbroken this backfired today.
We’ll be conducting a comprehensive review of our procedures, redundancy, and recovery — taking all measures to prevent an incident like this from happening again.
