I observed that the loopback address `91.108.0.1/32` was configured and verified, and pings to both `91.108.0.1` and `31.41.0.1` were successful. I decided to inform the ISP and EveLink about the connectivity issues, emphasizing the urgency and requesting their investigation. This was necessary because the issue was not on our end, and the ISP reported 100% packet loss to `10.3.3.2` with ARP entries in the STALE state. Despite follow-ups, EveLink did not respond promptly, highlighting the need for better coordination among all parties.
