Facebook is experiencing major Platform downtime tonight and all applications are down for most if not all users.
We’ve been seeing intermittent availability issues all week, but today’s/tonight’s outage is the most severe yet. According to a hot thread in the developer forums, some have not been able to ping apps.facebook.com for over 3 hours.
Obviously Platform downtime issues affect all application developers, big and small. The team is scrambling and we’ll pass along updates as they become available.
