Twitter's most retweeted tweet of all-time vanished from the platform on Tuesday.

Tweets that vanished include actor Cory Monteith's last tweet before his death, and Ellen DeGeneres' viral selfie — which racked up more than 3.4 million retweets at one point — and a breaking news post from @CNBC.

"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 can no longer be found on the singer's profile.

Editors at various media companies also said they noticed posts were vanishing.

Twitter said it was researching a bug that has caused some tweets not to be displayed.

Twitter's hiccups come as Facebook announces its $2 billion acquisition of virtual tech firm Oculus and as Instagram says it now has more than 200 million monthly active users. In total, Facebook now has 1 billion monthly active users of its apps, while Twitter's mobile app is utilized by 184 million users each month.
