YouTube cache node 50.151.220.26 not accepting TCP from my area (YouTube buffering)
Since at least 2026-09-11, YouTube playback stalls because the Google Global Cache
node inside the Comcast network at 50.151.220.26 is not accepting connections.
Evidence, gathered 2026-09-11 from two different machines on my LAN:
- Hostnames rr6---sn-bvvbaxivnuxqjvhj5nu-hp56.googlevideo.com and
rr11---sn-bvvbaxivnuxqjvhj5nu-hp56.googlevideo.com resolve to 50.151.220.x.
- TCP connections to 50.151.220.26 on ports 443 and 80 time out (no SYN-ACK).
- ICMP ping to the same address succeeds (~15 ms), and traceroute reaches it
via 50.150.167.218 > 50.146.186.158 > 50.151.220.26.
- The sibling cache nodes at 50.218.242.23 / .87 / .15 (hostnames ending in
-hp5e and -hp5l) connect in ~20 ms and work normally.
- My router has no firewall, IPS, or QoS rule affecting this address.
YouTube keeps directing my clients to the dead node, and each retry causes
multi-second buffering. Please have network engineering check the host at
50.151.220.26 or remove it from rotation. Happy to provide account details
and my public IP by private message.

Same cluster, same problem here (Broward County, FL). It's not just .26. 50.151.220.21, .24 and .26 all ignore TCP 443 from my connection. Ping to them works fine at ~12 ms, the SYN just never gets answered.
It breaks Play Store downloads too, not only YouTube. Android resolves rr9.sn-bvvbaxivnuxqjvhj5nu-hp56.gvt1.com to .24 and hangs on it for 130 seconds every time. Updates sit on Pending, then fail.
