----------------------------------+------------------------
When a bandwidth authority is configured with a nearby bandwidth server,
it measures nearby relays really high.
Its measurements for those relays don't help "to balance load across the
network such that a user can expect to have the same average stream
capacity regardless of path".

Instead, bandwidth authorities should use a geographically distributed set
of bandwidth servers. We can do this by:
* each operator setting up their own set of geographically distributed
bandwidth servers
* using one or more CDNs (#24506)
* sharing the current bandwidth servers between bandwidth authorities
Ideally, every bandwidth authority would use the same set of bandwidth
servers. That would eliminate one source of bias.
