According to its Current Status info - DNS Problem Suspected. I see the anchor is configured to use the following DNS Resolvers - 8.8.8.8 and 2620:74:1b::1:1. The anchor responds to pings and is reachable from the world. Also the resolvers 8.8.8.8 are 2620:74:1b::1:1 reachable from the anchor's uplink router. So apart from checking the anchor's connectivity and DNS resolvers I don't have much left to do in order to get the anchor connected again. Has anyone faced this situation before ?
