I never heard of Fosshost, but based on the name it was supposed to provide free hosting for open-source projects. What was the plan to sustain it?
Ampere had provided a very generous amount of hardware. Actually putting that hardware into places was a lot of finding DCs willing to support the project.
This is the problem of inherently unsustainable, poorly-governed, amateur operations: they're houses of cards waiting to fall apart.
If someone wants hosting, then pay for real VPS or colo. Electricity, rack space, and cooling are usually the limiting factors rather than data transit.
