We are defending against a denial-of-service attack, and will update status again shortly.

Update: the site is back up, but we are continuing to defend against and recover from this attack.

Update (9:46a): As we recover, users will experience some longer load times and slowness. This includes timeouts to API clients. We’re working to get back to 100% as quickly as we can.

Update (4:14p): Site latency has continued to improve, however some web requests continue to fail. This means that some people may be unable to post or follow from the website.

Site is down 23 hours ago

We are determining the cause and will provide an update shortly.

Working on missing followers for recently joined users 1 week ago

If you’ve recently joined Twitter, you may be running into a problem with followers. Specifically, some recently joined folks have reported losing their followers or have reported an inability to be followed. This includes seeing empty followers lists and zeroed follower counts.

We’re actively working on this problem and hope to release a fix soon.

Correcting follower and following counts 2 weeks ago

For some time, the follower and following counts we display have been incorrect for some folks. We’re soon to push a change that will address this issue. This means that the count you see in your sidebar should match what you see on your follower and following pages.

However, a consequence of this change is that follower counts will drop for some people. In particular, those with large followings may see significant changes as we correct for spam accounts and data inconsistencies. No legitimate followings should be affected—we’re just cleaning up artifacts in the system.
