We had a network outage for several hours yesterday afternoon (US time). Our buttons continued to serve into web pages but sharing was down and our website, analytics, and web services were unavailable. We truly apologize for the outage. We want to be a critical part of your social infrastructure and we can’t keep your trust unless our service is always available. We take this responsibility very seriously. The root cause was an administrative error by one of our service providers and we’ve made changes to reduce the risk of further network outages.
