The new Twitter web interface, which was officially rolled out to everyone just over a week ago, has suddenly been turned off for many users.
Twitter users (myself included) are instead being shown the prior version of Twitter. No word yet as to what the issue is, though the company posted to its status blog about an hour ago that it was performing database maintenance and that "there may be brief periods of elevated errors."
We’ve contacted the company for more details and will update when we know more. In the meantime, get your nostalgia hat out and enjoy the old Twitter.
