> This means their servers are very old ones that do not support x86-64-v2. Intel Core 2 Duo days?

This is not always a given. In our virtualization platform, we have upgraded a vendor supplied VM recently, and while it booted, some of the services on it failed to start despite exposing a x86_64v2 + AES CPU to the said VM. Minimum requirements cited "Pentium and Celeron", so it was more than enough.

It turned out that one of the services used a single instruction added in a v3 or v4 CPU, and failed to start. We changed the exposed CPU and things have returned to normal.

So, their servers might be capable and misconfigured, or the binary might require more that what it states, or something else.

A developer on the ticket writes: "Our machines run older server grade CPUs, that indeed do not support the newer SSE4_1 and SSSE3"

Ooh. They are at least ~15 years old, then. Maybe they have scored on some old, 4 socket Dell R815s. 48 cores ain't that bad for a build server.

It's kinda good they use such old systems, as the vast majority of pollution occurs during manufacturing of devices since we usually use them only a handful of years. Iirc the break-even point was somewhere around 25 years, as in, upgrading for energy efficiency then becomes worth it (source: https://wimvanderbauwhede.codeberg.page/articles/frugal-comp...). 15 goes a long way towards that!

On the other hand, I didn't dig very deep into the ticket history now but it sounds like this could have been expected: it broke once already 4 years ago (2021), so maybe planning an upgrade for when this happens again would be good foresight. Then again, volunteers... It's not like I picked up the work as an f-droid user either

		While I appreciate the sentiment, I think you may be misreading the "Emissions from production of computational resources" section of that link. It says for servers that 13-21 years is the break even for emissions from production vs consumption. The 25 year number is for consumer devices like phones and laptops. I would also argue that average load on the servers comes into play.

		Moot point imo, no one says they have to buy new hardware. Used, affordable, but still much more modern hardware could still save them plenty on power usage and replace several systems with one.
