For close to two hours, Monday afternoon, Facebook users were having difficulties in updating their status, post pictures and the like.
Attempts by users to update on the social networking site yielded this message: “There was a problem updating your status. Please try again in a few minutes.”
The peculiar bug was partially fixed after a couple of hours as some are able to operate their accounts accurately – many still face difficulties.
The development raised dust among users most of whom initially thought the issue was not a common problem.

Consequently, Iain Mackenzie, the European communications director for Facebook, confirmed the issue on twitter : “We are aware that some people are having problems posting to Facebook and we’re looking into it.”
According to Michael Allen, Director of APM, Compuware, the outage would potentially affect “billions of people.”
“If you look at the Outage Analyser service, at least 3,587 other domains were impacted; although the actual number is likely to be far greater. This is because many other businesses and websites are connected to Facebook. For example, Facebook is used to enable people to log in to many other sites and applications. Any organisation that is seeing errors or slowdowns with their own site or application this afternoon, should check to see if they are relying on Facebook services before they start fire fighting as this might be the cause.

However, everything seems to have come back to normal.

Users, did you experience this?
