NetBSD archive servers are down

[Kobzol]

The NetBSD archive servers (https://archive.netbsd.org/pub/NetBSD-archive/NetBSD-9.0/) from which we download NetBSD sources on CI have not been working for the past ~24 hours. This means that the dist-x86_64-netbsd CI job cannot rebuild its Docker image.

Right now, it doesn't block CI, because we use a cached Docker image, but in the upcoming days the cache might break, and then this would immediately start blocking our CI if it does not get resolved.

Zulip discussion about this can be found here.

CC @he32, as you are listed as the Designated Developer here. :) Any hints on how to resolve this or even where to report the problem? Thank you!

There appears to be an expired certificate involved. I've contected the admins, who will hopefully take care of fixing this. Best regards, - Håvard

Thank you! In the meantime, we have put the files into our own mirrors (#138507).

We now mirror the sources.
