Hi, Let me answer that with both my wanna-build and DSA hats.

I'm a buildd The 32-bit buildds are running quite stable besides a few disks dying, given their age. However they are difficult to manage remotely (they don't start automatically after power cycle) and more importantly they are slow, only have 4GB of RAM and are limited to 3GB address space. We were using them until recently, but given that the kernel has gotten support for building armel and armhf in a chroot, they are currently disabled, although they are not yet decommissioned. > admin for those ports and the machines on this site and I'm not aware > of problems with the 64-bit machines, and I don't get Nagios messages > about them having gone down/back up, like I do about the armhf/armel > hardware.

The 3 arm64 boards running at ARM are pretty fine, we do not have any issues with them, however they start to be old. On the other hand we have many issues with the Ampere servers hosted at UBC and the Applied Micro servers hosted at Conova. All of them crash regularly (a few times per week in total) and need a powercycle. In addition the bullseye kernel does not work on Applied Micro servers, so we are currently stuck with buster on them :(. > I thought I was getting all monitoring > messages for machines on this site My guess is that you don't receive any notification as the buildds running on arm64 hardware are VMs on the above hosts. From that point of view, the buildds are running fine, however the underlying hosts are not. > So if there is an issue there we have a communications problem as well > as a hardware problem.

It's becoming urgent to get new ARM64 hardware to overcome all those issues, and we (DSA) failed to find new hardware to buy at a decent price.
