I have two projects currently hosted on Vercel. Their custom domains are unreachable when using Orange Morocco’s mobile network, although their vercel.app deployment URLs work normally on the same connection.
Affected custom domains:
Working Vercel deployment URLs:
Observed behavior:
-
Both custom domains do not load through Orange Morocco.
-
Both
vercel.appURLs work normally through Orange Morocco. -
The custom domains work immediately when I enable a VPN on the same Orange connection.
-
The custom domains also work normally through Maroc Telecom and Inwi.
-
The DNS configurations and SSL certificates appear valid.
-
The problem affects two separate custom domains and Vercel projects.
-
A third custom domain previously had the same issue while hosted on Vercel. After I moved that project to Netlify, its custom domain became accessible through Orange Morocco.
The projects and deployments are clearly operational because their vercel.app URLs work. The issue appears limited to the network path or IP addresses used by Vercel for custom domains when accessed through Orange Morocco.
This may indicate a routing, filtering, peering, or BGP issue between Orange Morocco and Vercel’s custom-domain infrastructure.
Could a Vercel team member please review this and escalate it to the networking or Edge Network team? I can provide traceroute results and additional diagnostics if required.
