Resolved: Web Isolation Connectivity Issues for Web Security Service


On March 23, 2022 starting at 22:30 UTC, Web Security Service (WSS) customers may have experienced issues while browsing using Web Isolation service. The issue affected only a subset of customers of WSS, who were using a non-updated machine.

It has been identified that the problem occurred due to updated certificates in Web Isolation, which out-of-date machines were not able to validate and trust.

As of 10:30 UTC on March 24, 2022, the service is fully restored. This incident is now resolved.
