[tor-relays] Question: Relay speed South Africa

Hello experts,

I have, from the same provider, two VPS with same specs (also same port speed of 200MBit/s, verified via speedtest-cli) - one in Germany, one in South Africa. Whilst the German one behaves as expected (two fast relays on it), the two relays in South Africa won't really get up to speed - barely traffic, and advertised bandwidth below 2MB/s .

In general, search for country:za on metrics does not really look too impressive.  Do you have any idea about the reason, i.e. why, despite the VPS having the bandwidth, the relays do not get up to speed?

Thanks - C.
