Custom domain unreachable from Oman - Regional routing issue with 216.198.79.0/24

Adding another confirmed, independently-diagnosed data point — this looks like a broader pattern, not an isolated case.

My setup:

  • Domain: phoenixftoman.com
  • Vercel project: phoenix-globnet-site
  • Location: Muscat, Oman
  • ISP: OmanTel (AS28885)

What I found, using the official vercel-connect-debug script against my project’s assigned edge IPs:

IP Result
216.198.79.3 :white_check_mark: HTTP 200, ~12ms
216.198.79.67 :white_check_mark: HTTP 200, ~9ms
216.198.79.131 :white_check_mark: HTTP 200, ~8ms
216.198.79.195 :cross_mark: Connection timed out after 3s (ping succeeds — so it’s a filtered/dropped connection, not a routing failure)
64.29.17.3 :white_check_mark: HTTP 200, ~9ms
64.29.17.67 :white_check_mark: HTTP 200, ~11ms
64.29.17.131 :white_check_mark: HTTP 200, ~8ms
64.29.17.195 :white_check_mark: HTTP 200, ~8ms

So 7 of 8 assigned addresses work fine — only 216.198.79.195 is blocked from my specific network. My custom domain’s originally-assigned A record, 216.198.79.1, also times out from this same connection (a different address in the same /24, same symptom).

This appears to be the same underlying issue reported across several other threads, each affecting a different specific IP within the same new ranges:

Given how many independent reports this now has, across multiple ISPs and at least two countries, this looks like a genuine Vercel Anycast/edge routing issue specific to the newer 216.198.79.0/24 and 64.29.17.0/24 ranges — not something any of us can fix on our end. Each affected user seems to have a different specific IP blocked within these ranges, which suggests inconsistent regional routing/peering to parts of this new pool rather than a single blanket block.

Current workaround: I’ve set up GoDaddy domain forwarding to my .vercel.app URL, which works since it happens to resolve to a working address. Would like to move back to a direct custom domain setup once this is resolved.

I also raised this via Vercel support chat — the agent confirmed it as a real routing issue and attempted to escalate to a support case, but case creation for “Domains > DNS Configuration” is gated behind a paid plan, so posting the full evidence here instead, where the other confirmed reports live.
