Extremely high volume of whales 2 days ago

We are experiencing an outage due to an extremely high number of whales.  Our on-call team is working on a fix.

Update (5:18a): We are recovering from this incident. A sudden failure coupled with problems in switching to a backup system produced a high number of errors for around 90 minutes. This made the site largely inaccessible. No data was lost or compromised during this outage.

SMS delivery temporarily disabled 1 week ago

We have temporarily disabled the SMS delivery of tweets. We are continuing to work on a fix for the misdelivery problem noted earlier and will turn the service back on as soon as this is resolved.

Update (11:47p): This issue has now been fixed. Both updating from SMS and receiving messages via SMS should work as expected.

Recovered from tweet delivery problem 1 week ago

Earlier this evening, users would have noticed missing tweets in their timelines. We have now recovered from this problem and timelines will be updated normally.
