It looks like Twitter has gone down and it is far more serious than the fail whale we are used to seeing. The website itself is not inaccessible and it looks like it has suffered some kind of massive outage.
Right now there is no update on the status blog too. We have reached out to Twitter to find out what has caused the outage.
Update #1: Twitter posted a message on their status blog confirming the downtime
Users may be experiencing issues accessing Twitter. Our engineers are currently working to resolve the issue.
Update #2: Google Chrome has started displaying messages to users on Twitter being inaccessible for several users as well
Update #3: Looks like Twitter is back up
Update #4: And it appears like another Twitter outage
Stay tuned for further updates….
