On June 9th, 2020, IBM Cloud data centers suffered a global outage that caused connectivity issues for many of the web sites and platforms utilizing the service, including BleepingComputer. The outage started at approximately 6:05 PM EST, and services were restored around 9:00 PM. The next day, IBM updated an announcement previously made during the outage stating that an external network provider caused the issue.
