[tor-relays] Tor Relay Automatic PMTU Testing

Greetings,

I believe there is a larger sized guard relay that has been having MTU issues for about a week. All connections with packets above a certain size are dropped. This results in partially loaded or broken webpages, broken file downloads, etc. Do Tor directory authorities test MTU (implicitly by speed test?) when testing relays?

Wondering if anyone else noticed this or if it would be handled automatically by dir authorities.

Thanks all
