Anycast 45.90.28.0/24 and 45.90.30.0/24 unreachable from Verizon Fios Washington DC, zepto-xrs PoP not answering anycast

Since before 11:55 EDT on 28 Sep 2026, plain DNS to 45.90.28.162 and 45.90.30.162 times out on UDP 53, TCP 53 and TCP 443 from Verizon Fios in Washington DC. 1.1.1.1 and 8.8.8.8 answer normally from the same hosts, and your ultra low latency servers are reachable (zepto-xrs 4 ms, anexia-mnz 7 ms). The Setup tab on my.nextdns.io also shows "Error while checking the current status". The diag tool was run at 12:47 EDT and the report was sent, but the window closed before the link could be copied; full output is below. Traceroute to 45.90.30.0 ends at 199.119.65.14 inside the zepto-xrs site, and test.nextdns.io (199.119.65.94) also times out, so that PoP appears to announce anycast it is not answering. Traceroute to 45.90.28.0 ends after 128.241.8.171 in NTT. Two Windows DNS servers forwarding to the profile addresses fail for the whole network.
