Twitter is currently investigating a widespread service problem.
Update: at 3:27 ET Twitter posted the following update:
Has the world screeched to a halt? Nope.
But confused Twitter users can't be blamed for asking – the microblogging site has confirmed that it's having difficulties with its timeline updating. In other words, we're tweeting to ourselves.
Word of the outage came from the official Twitter status monitor, which told visitors "We are currently investigating a problem causing many users’ timelines to be delayed. We will update with status here shortly." The site isn't exactly down, as downforeveryoneorjustme tells us – it's just not updating.
Twitter, of course, is no stranger to downtime, displaying the infamous fail whale when it can't keep up with demand, but today's outage is something this tweeter hasn't seen before.
