It’s not just you – Facebook is down for many users. The outage appears to have hit around 3:45 EST.

This is the fourth such outage for the social network since June. The last one happened at the beginning of August.

This isn’t just frustrating for Facebook users, as Facebook itself suffers from extended outages. Reports indicate that a 20-30 minute outage can cost the company over $500,000 in ad revenue.

Frustrated or not, whatever you do, please don’t call 911 about it.

We’ll update this accordingly…
