Late in the week, an outage at Amazon Web Services affected numerous websites. After the disruption, which lasted from Thursday to Friday, Amazon revealed the reason.

As per a notice on the official AWS status page, the outage was caused by a “thermal event leading to a power loss” at a data center located in northern Virginia, indicating that some equipment had overheated. This prompted Amazon to reroute traffic from that data center’s “Availability Zone” on Thursday afternoon. By early Friday afternoon, Amazon had reinstated its cooling systems, beginning the process of restoring services.

“Our primary focus during the incident’s mitigation strategy was to restore our cooling systems’ capacity. By May 8 at 1:50 PM, we managed to stabilize the cooling system capacity to pre-incident levels, which allowed us to recover most of the affected EC2 instances and EBS volumes,” Amazon mentioned. “A limited number of instances and EBS volumes are still affected, and we are continuously working to recover all remaining impacted resources.”

The outage affected widely used apps such as FanDuel and Coinbase, hindering users from placing bets or trading as they normally would, likely leading to some annoyance on Thursday and Friday. Nevertheless, the issue seems to be largely resolved now, so you can likely proceed with your NBA playoff prop bets if desired.
