Reponding to both of you...

I now have 3 more basic Synquacer machines in my posession, ready to
order new cases, RAM, etc. (They ship in desktop cases with a single
1TB hard drive and 4 GiB of RAM.) Again, I'm hoping to pick more up in
the future, but supply is still limited.

Again, I'll reiterate - these machines are *not* fast for
single-threaded workloads but they have a lot of cores so it's
perfecty reasonable to run lots of things in parallel. For my own
build testing, I've been running up to 6 sbuilds in parallel for
better throughput while lots of our builds don't parallelise
individually. They should also work well for multiple VMs running in

So, practical questions...

Hardware setup: I've configured the earlier 3 as buildds in little 1U
cases with 32GiB RAM and mirrored SSDs, but for $reasons they're not
yet installed and running. I'm assuming that a similar spec would be
wanted for autopkgtest/ci and reproducible builds? If so, we'll need
to ask for approval for funds for that - it cost ~£750 per machine to
do it. I had offers of funds at DC18 which I'm about to chase to help.

Hosting: Talking to DSA, it seems they're not too keen on hosting /
managing new machines for these projects. What are current hosting
arrangements for you folks?
