Tweetdeck went down for hundreds of users who were unable to load the site.
According to Down Detector, which aggregates user reports of issues with apps and websites, 352 users reported being unable to access the site, and instead received an error page, that read ‘tweetdeck.twitter.com can’t be found.’
Tweetdeck was acquired by Twitter for $40 million in 2011 after operating as its own independent application.
The application allows users to aggregate tweets and view accounts in a consolidated dashboard.
The outage, while not widespread, came in the wake of a high-profile hack on Twitter which saw the accounts of 130 celebrities compromised in an effort push a Bitcoin scam.
The hack saw former US president Barack Obama, Microsoft founder Bill Gates and rapper Kanye West among the high-profile accounts affected.
Accounts of Elon Musk, Joe Biden, Jeff Bezos, Kim Kardashian West, Mike Bloomberg, Apple and Uber are also known to have been hit.
Tweets were simultaneously posted promoting a Bitcoin scam which promised followers free bitcoin if they transferred funds to a specific digital wallet.
