Infrastructure provider outage

One of Flathub’s infrastructure providers experienced an outage, which caused multiple services to become unavailable. This issue has now been resolved by the provider.

Any builds that were affected during the outage have been restarted.

• If a pull request test build is still failing, maintainers can restart it by commenting bot, build on the pull request.
• If an official build from a merged pull request is broken, please open an issue.
