Oh, OK. Glad to see not everybody who rents virtual private servers also
caps their bandwidth. It happened to me so many times that I could even
bet that this was the issue here, but looks like it's not.

Since atlas is down, I have looked at the votes here:
https://consensus-health.torproject.org/consensus-health.html

and it looks like your relay has a measured by authority 'bastet' of
355. That is not a big value. The other authorities measured this:

278;
355;
367;
803;

So it looks like the speed was pretty much the same for the measurements
performed on your relay by different servers on different networks. If
you say you are sure there is nothing automated (at either OS level,
hypervisor level, local router/network level or something upstream) that
could throttle this in case of continuous high usage, there's not much
you can do other than waiting some time to see the next speed measurements.
