Twitter is currently in a weird limbo. After having issues with missing tweets and incorrect tweet counts yesterday, and being down for the better part of the night, it is now up, but it has a different problem: all its tweets are gone.
All the Twitter accounts we've checked, even Twitter's official ones, are completely empty: they seem to work, but there are no visible tweets in the timeline.
Twitter status blog has some info on the situation:
"We’re currently experiencing site availability issues resulting from the failed enhancement of a new approach to timeline caching. Our infrastructure and operations engineers are currently working to resolve this. We’ll update you soon with an ETA.
10:17 PM PDT: Users may temporarily experience missing tweets from their timelines. They will be restored shortly.
11:51 PM PDT: We’re recovering from the site outage. Remember, users may temporarily experience missing or duplicate tweets from their timelines. Normal timelines will be restored shortly."
So, there's no need to panic: our tweets are (probably) not gone completely. Still, it's a bit worrying seeing a completely empty timeline when you know it should be populated by thousands of tweets.
