I don't know: but it seems that the issue with Cogent affects a majority of the bandwidth authorities. Perhaps it's more than just cymru that's affected?
If you send me the address of your HTTPS server, I can ask a relay operator to do a traceroute and speed test. Or you can do one to 51.15.50.10 (which used to get multiple megabytes a second, but has dropped to 500 KB/s).
The operator gets 194 KB/s over a 14-hop path from Paris to a bandwidth authority server in Erlangen, Germany. (Paris, Amsterdam, Hamburg, Erlangen.)
This looks like it's a problem for any AS that transits via Cogent. It's certainly not cmryu-specific, or even specific to North America.
It appears that the Tor bandwidth authorities really should be down-rating Exits on these networks.
It would still be great to make sure we don't have a single point of failure for the bandwidth authority HTTPS server. But I think we're ok otherwise.
