We'd like to provide some additional details on the recent service degradation many of you experienced in the European region when using the Collaborate service on May 4 and May 5 (2018). Unity services rely on a third-party message delivery platform to relay important notifications around changes to the services. This service experienced degradation in its European data centers which ended up causing a degradation of Unity's identity management service used by all Unity cloud services, including Collaborate. In addition to insulating our services from this type of degraded response from dependent services, we are also taking steps to address cases where the Unity Editor slows down and becomes unresponsive when Collaborate is enabled and unable to communicate with our identity service. We apologize for interrupting your work and will ensure this type of issue does not occur again. Please feel free to contact us if you require more information or need additional help resolving any other impact this outage may have caused.
