[isabelle-dev] AFP submission + Jenkins maintenance

[Lars Hupel]

Dear Isabelle developers and users,

our provider for some of our VMs has announced a scheduled maintenance,
lasting from November 8 to November 11.

The following parts of our infrastructure will be disrupted:

- AFP submission service
- "nightly slow" builds

Since we're in the release phase anyway, I don't think missing "nightly
slow" builds are a problem.

Everyone who considers submitting an AFP entry, please hold off until at
least November 12.

Cheers
Lars
