I can confirm that Twitter for the web (mobile works for some) has been out for users in Nigeria and Ghana for quite a long time (over 20 mins). Are you affected too? What is your location?
According to the Guardian, Twitter confirmed the worldwide outage by tweeting from their @support account. Realising the issue, they had to email the tweet so that news agencies could actually see it.<p><a href="http://www.theguardian.com/technology/2016/jan/19/twitter-down-over-web-and-mobile" rel="nofollow">http://www.theguardian.com/technology/2016/jan/19/twitter-do...</a>
Twitter is quite a critical infrastructure to have a single point of failure.<p>I just logged back into my APP.NET account <a href="https://alpha.app.net/" rel="nofollow">https://alpha.app.net/</a><p>I know it's wishful thinking to assume this could revive it but I wish Dalton would email everyone to inform them there is still a way they can argue with strangers online. :)<p>Jokes aside, most people have zero ways to interact with people they had been in constant touch with via Twitter now that it is down.<p>Crazy!
It is down for me here in Germany as well.<p>Just posting the status link <a href="http://status.twitter.com/" rel="nofollow">http://status.twitter.com/</a>
They are aware.
