Twitter down, the fail whale returns (Update: Now back)

It's the end of the world. Twitter is down. Global panic will no doubt ensue. Twitter has issued the following statement:

"Some users may be experiencing issues accessing Twitter. Our engineers are currently working to resolve the issue."

The service went down just before 3:30pm UK time. The downtime is affecting both the Twitter.com website and its apps. 

We are monitoring the situation and will keep you posted. 

Twitter seems to have returned.
