Twitter investigating 'error messages'

Downdetector, which tracks outages by collating status reports from a number of sources, including user-submitted errors on its platform, showed more than 48,000 user reports of outage.

The micro-blogging site said on its status page that it is yet to determine the scope of impact on its users.

Some users on Reddit complained of being logged out of their Twitter account while others said they could not send or retrieve tweets.
