Hi, The loss timer as defined in RFC 9002 A.8 has an exponential backoff component "* (2 ^ pto_count)" that is unbounded. This means that if there is a lengthy network outage, QUIC may not recover until up to twice the length of the outage because it will wait for the timer to expire and the timer doubles without bound. For example, a network outage of one minute could translate into a QUIC "outage" of two (on average) to three minutes (unlucky upper bound).
I think there should be a limit to the loss timer. I don't know if the spec should provide a specific limit but I think it should be allowable to set an upper bound on the loss timer in the 8-64 second rage. Thank you for your consideration. Cliff Cordeiro
