Facebook was unavailable for users in some countries in Europe, the Middle East and Africa for two hours on Wednesday because of what the company called “technical difficulties.”

Countries affected included the UK, Ireland, Pakistan and South Korea, according to Twitter posts tracked by the BBC.

“Today we experienced technical difficulties causing the site to be unavailable for a number of users in Europe,” Facebook said in a statement. “The issue has been resolved and everyone should now have access to Facebook. We apologize for any inconvenience.”

Some on Twitter had fun with the occasion by using the hash tag #facebookdown:

@KrisPrajapati: #FacebookDown. Worker productivity rises. US climbs out of recession.

@Dirtgamerz: “Facebook est down, les animaux de Farmville vont mourir de faim #facebookdown.” (“Facebook is down, the Farmville animals will die of starvation.”)

@106jack: “#facebookdown - Thank God we still have Twitter to tell everyone what we had for breakfast. (Porridge with raisins)”

Facebook, which has about 845 million active users, announced plans to raise $5 billion last month in an initial public offering expected to value the company at between $75 billion and $100 billion, the UK’s Daily Mail reported.

According to NetworkWorld, there was another brief outage reported the day after the company filed for its IPO.
