I don't have any post-mortem details of the cluster outage that happened on the weekend, but the "mirror.clearfoundation.com" issue is now resolved. This is what I do know:
When the ClearFoundation mirror system does not have an updated list of available mirrors (which should never happen?), the system falls back to a single mirror.clearfoundation.com mirror instead a list of mirrors like mirror3-toronto, mirror2-dc, etc. That single fallback hostname was not working properly, hence all the issues.
An update will be available to ClearOS Professional in just a few minutes. I would expect the Community Edition to get the update in the next 12 to 48 hours. Why the difference? There are two sets of repositories:
- ClearCenter repositories for paid apps and Professional Edition extras
- ClearFoundation repositories for the base operating system
The ClearCenter repositories and mirrors have a quick turnaround time, while the much more sophisticated/complicated ClearFoundation build system, repos and mirrors have a longer turnaround time. I'm not as familiar with the ClearFoundation systems, so I don't know exactly when the update will appear.
PS - feel free to use the workaround suggested by Eric!
