Just to expand on this, we *in principle* have three kinds of ‘mirrors’ (servers)

 - TerraSync 
 - FGaddon
 - downloads

Each of these has some nuances, but also for all three, one of the mirrors was us1mirror (Heliohost), which recently had some issues with our VPS / traffic, and is being re-created. The problem is us1mirror was the source-of-truth for the CDN, so it’s also down. 

In the medium term we’re going to move the TerraSync source-of-truth to the same host as the CDN (Bunny,net) since this will be more flexible than Heliohost, for the same recurring cost.

The good news is Ibiblio exists as source-of-truth for FGaddon and downloads, the bad news is some people (including Chris) were using us1mirror as source-of-truth, *because I told them to*, but I think we’re at the point of considering Heliohost as best-effort, not something really reliable. (The web servers also seem to get stuck / fall over once per month, no idea why…)

So we’re /probably/ going to gradually wind down that server in the next few months in favour of other hosts, such as de3mirror (Hetzner).

Kind regards,
James
