1. Many places in the world don't ever need cooling

2. If servers are distributed then downtime is distributed, you can virtually guarantee that some of the servers over the world will be online so you can get effectively 100% uptime, something that is not possible in a data center

3. To serve tokens you need very little bandwidth, it's just text in and out

4. All of this is down to the HW and the SW itself, not the building. That is, the box that's being deployed.

5. Just switch to a different server until the problem is resolved, in this model there is no urgency. You just need redundancy which you can afford with how much cheaper this would be.
