03:53am UTC: We are hearing some reports of service outages for some sites. We are investigating the cause now and hope to have a resolution soon.
Update 04:19am UTC: The outages were due to a network problem at our datacenter. This is now resolved and we're waiting on more details on what was wrong.
Update on cause: the outages were due to a network problem at our datacenter where there was a denial of service attack and they mitigated the attack. This DoS attack was larger than what they've normally experienced, so they are in the process of increasing their core network bandwidth to improve resilience in these situations.
