We share the hosting with other corporate services so we unfortunately
won't be able to provide bandwidth statistics.

The total number of bare metals we have running is:

8 hypervisors
7 CI runners

Load is usually pretty low (6-8 on load15) on hypervisors, regarding
runners we're currently not gathering any utilization statistic but I
expect the load to considerably higher on peek hours when multiple
concurrent jobs are running.

The datacenters in question are located in: Raleigh, North Carolina,
Phoenix, Arizona and one of them lives in London. We're currently
working to reduce the amount of hypervisors for better maintainability
and cost reduction.

What we mainly use within AWS are S3 buckets in the following 2 regions:

us-east-1
us-west-2

Let me know if there's anything else you need on this side, thanks!
