Twitter was struggling to restore service to all of its users on Wednesday after a worldwide outage hit the microblogging platform’s website and its dashboard management platform TweetDeck, affecting thousands.

“The issue is just about fixed,” Twitter told users in a post at 7:09 a.m. ET. “You should be able to access Twitter as usual. If not, give it a few more minutes! Thanks for waiting.”

Nevertheless, more than two hours later, many users were still griping that they couldn’t log into or otherwise access Twitter and TweetDeck, which is used by reporters and other content creators for monitoring tweets from multiple Twitter accounts.

“I’m still getting plenty of access errors in Tweetdeck (teams stuff and main account) with some lovely flashing red banners at the top. Same on both the web version and desktop app,” user Chris Cornutt tweeted at 9:56 a.m. ET.

“Unfortunately @TweetDeck is still behaving like it is in a hyperactive disco,” tweeted user Martin Baker.

Earlier, outage monitoring website Outage.report had received more than 4,000 reports of the incident globally, including Japan, Canada and India.

“You might have had trouble Tweeting, getting notifications, or viewing DMs. We’re currently working on a fix, and should be back to normal soon,” the company said earlier Wednesday in a tweet, which did not give further details.

A Twitter representative had earlier told Reuters that the company was investigating issues with TweetDeck. Log-in attempts earlier by users of TweetDeck seemed to be redirecting users to Twitter’s website.
