Hello torix,

I think I remember Roger Dingledine saying somewhere that bridges' ips gradually get learned and put on ban lists.
I have some bridges bought for the year. When renewal time comes up, does it make sense to let them go and buy new vms for the next year rather than renew them? I don't know if it matters what pool a bridge is in.
Yes, is good to rotate the IP addresses of bridges. What you say is correct. It doesn't matter what pool you are in.
Only private bridges are good to be stable, as they are manually handled and you will need to notify the users of this bridge of the new IP address. But if you didn't configure your bridge specifically to be a private bridge (with the 'PublishSherverDescriptor 0' option) and handled by hand your bridge data to bridge users you are not running one and will be good if you rotate the IP address once in a while.
Thanks for running a bridge.
