Yesterday, Twitter experienced issues loading new tweets for nearly one hour and today it appears to be the turn of Facebook, as a number of users are currently unable to log into the social networking site due to an error.

Update: It appears that Facebook is working as usual again. The issues lasted for around 90 minutes.

TNW staff in North America and Asia are not having issues accessing Facebook, but other users are less fortunate. According to Web monitoring service Downrightnow.com, Facebook has experienced a ‘Likely Service Disruption’ since 18:00 PDT, 02:00 BST — that’s more an hour ago at time of writing.

Users that are affected are being greeting with the below message — via @niw — that explains that a “site issue” has made their account temporarily unavailable. The message provides no further details.

It is not clear if the issue is restricted to certain regions or is affecting users worldwide, plenty have taken to Twitter (see search) to vent their frustration:

As we said yesterday in the case of Twitter, downtime is never welcome for any Internet site, particularly those that are used on a daily basis by millions. Facebook will be looking to fix whatever the problem is quickly.

We’ve reached out to Facebook for more details.
