[tor-relays] Guidelines for lifetime of a bridge?

Hi. Is there a guideline for how long a bridge should exist on a particular IP address? For example, does it make sense to keep a bridge on one IP address forever? Or is it better to move a bridge to a new IP address periodically, perhaps every 120 days? I ask because I saw traffic to my bridge ramp-up fairly steadily, and then quickly drop-off to a low number of clients per day. Thanks! hope you are all well t -- Tim Sammut ~ @t1msammut ~ tim@teamsammut.com Ford-Mozilla Fellow at Amnesty International
