> [@torix](#): > > Have both these bridges been most likely “found out” by now and I should retire them and start with new ips? How long should a bridge last? Hey @torix, that’s a great question. If you have an average of 1500 daily connections, it seems your bridge is very useful, and rotating the IP address might not help more users. You can check your bridge’s country stats in this file: `/var/lib/tor/stats/bridge-stats` or on \*BSD: ` /var/db/tor/stats/bridge-stats`. If you find that most users are coming from countries that block Tor (Russia, Iran…), I’d say that rotating the IP will frustrate a lot of users more than it will help. Maybe you could allocate a new bridge and monitor when the IP is blocked in China, then it? Usually when the GFW detects a bridge, it blocks the IP address (and not just IP:Port). You can use this site to test your bridge’s reachability: [https://www.itdog.cn/ping/](https://www.itdog.cn/ping/).
