Twitter's most retweeted tweet of all-time vanished from the platform on Tuesday for more than five hours.
The curious case of the vanishing tweets came to light when users of the social media service began buzzing late afternoon that tweets were mysteriously disappearing.
Tweets that vanished included actor Cory Monteith's last tweet before his death, Ellen DeGeneres' viral selfie—which racked up more than 3.4 million retweets at one point—and a breaking news post from @CNBC. Editors at various media companies also said they noticed posts had vanished.
"At least I got the tweet framed before it got deleted," a fan of Justin Bieber posted along with a frame showcasing a tweet that could no longer be found on the singer's profile.
