User search and Facebook updating are temporarily...
We are working to restore both of these services.
Update: User search has been restored.
Improperly sized images
We’re investigating a bug that causes improperly sized images for backgrounds and avatars. This should only be affected images uploaded in the last several days.
Update (2:01p): We’ve pushed a fix for the improper image upload problem. This will cause JPG upload problems for some users but resolves the more serious mis-sizing issue. We will do a second update to resolve the JPG issue.
Some t-mobile delivery problems
Some T-Mobile users will not be receiving all updates via text due to a problem with our provider. We’ve resolved this issue but users will see some missing updates via SMS.
Problems reaching search?
Due to a DNS error, some users may have problems reaching search.twitter.com. The problem has been corrected and you’ll be able to reach the site as soon as the change propagates through DNS to you.
Update on site reliability progress
The site has been sluggish the past couple days, but we’ve been making good progress on some of the more serious bugs.
We’ve largely resolved the database inconsistency issues that were responsible for a wide range of problems. These include: fluctuating direct message counts and missing updates. Some older updates (from before 3/25) may still not have reappeared. But new updates...
User deletion and restoration temporarily disabled
We’re tracking down a bug that is causing trouble for those using these functions. We’ll re-enable as soon as it’s fixed.
Update on service issues
We’ve just released an update that solves some of the slowness issues we’ve been seeing lately. However, more work remains. Here are the top issues we’re still working on:
Problems with following: Folks are seeing erroneous messages about being “over the follow limit.” Also some changes with following seem not to apply right away or to stall out.
Missing updates:...
Some users experiencing missing tweets
Some users will be missing updates from their timeline due to a database issue we’re actively working to resolve. This won’t affect everyone and the updates are not permanently lost. Thanks for being patient as we work this out.
Update (4:40p): We’re making progress on the missing tweets problem. As of right now, updates should be flowing through normally. However, there will be...
Update on bugs: device registration and image...
We’re seeing lots of reports of “error D1051” from people trying to register a phone on twitter.com. We think this is being passed on from the provider we use to send SMS.
Also, many people are running into problems when trying to upload images for either avatar or background image (PNGs or JPGs under 700kb should be accepted.)
We’re working on both of these critical...
Unplanned maintenance
We’re recovering from an unplanned maintenance window and will be back soon.
Update: Actually, it turns out that while we had slowness, we never were down. Sorry (but grateful) for the false alarm.
Some delays on followings, direct messages
Users will experience delays of up to 45 minutes in receiving direct messages. Also, some changes to follower/following relationships may be similarly delayed.
This should not affect tweets or timeilnes.
Some missing updates, actions
For about an hour earlier tonight, some users would have experienced gaps in their timelines or inconsitencies when trying follow. We will be rebuilding the missing statuses and will also work to correct the discrepancies with follower/following relationships introduced during this time.
SMS maintenance tonight
Our upstream SMS provider will perform planned maintenance from 10:00 to 10:30 PDT tonight. This maintenance will not affect AT&T and T-Mobile customers; customers of other carriers will not be able to use SMS with Twitter during this period.
Working on SMS issues
We’re currently working with our SMS provider to fix delivery problems with all inbound and outbound SMS. Delivery seems to be returning to normal after an a partial outage that started 45 minutes ago.
Update on inconsistencies
Some folks may experience inconsistencies in information seen on Twitter. Specifically, you may see a fluctuation in follower counts, direct messages or other data. We’re working to resolve this.
Virgin Mobile SMS service restored
Due to a problem with our upstream provider (not on the Twitter or Virgin Mobile side), Virgin Mobile text messages were not being delivered correctly. This problem has now been resolved.
Inbound SMS Delay
We’re seeing a delay of several hours in posting inbound SMS. As a result, updates that you post via text message won’t show up on Twitter right away.
We’ll have a fix out for this shortly. When the fix, is made live older updates will be posted as new. Apologies for the delay.
Signing In Back to Normal
We’ve fixed the problem folks were having with signing in to Twitter.
Problems logging in
Some users are receiving an error while logging in. We are fixing this issue now.
Power failure this morning
We experienced a brief data center power failure this morning affecting a small number of servers. Site performance was degraded for 5 minutes.
