Hi Vercel Team,
I'm experiencing a region-specific issue with my Vercel deployment and would appreciate your help investigating it.
Environment
-
Framework: Next.js
-
Hosting: Vercel
-
DNS Provider: Hostinger
Deployment URL
https://wattintelligence.vercel.appCustom Domain
https://www.watt-intelligence.comhttps://watt-intelligence.comProblem
The application works perfectly from India and other locations we've tested.
However, users in Oman consistently receive:
ERR_TIMED_OUT
when accessing the custom domain.
The important observation is:
✅ https://wattintelligence.vercel.app works from Oman.
❌ https://www.watt-intelligence.com times out from Oman.
This issue has persisted for more than two weeks.
DNS Configuration
Hostinger DNS:
A@216.198.79.1CNAMEwww20d16cfa170e201c.vercel-dns-017.comThere are no AAAA records configured.
These records match Vercel's current DNS recommendations.
DNS Resolution (India)
ISP DNS
nslookup watt-intelligence.com216.198.79.1nslookup www.watt-intelligence.com20d16cfa170e201c.vercel-dns-017.com216.198.79.164.29.17.1Google DNS
nslookup watt-intelligence.com 8.8.8.8216.198.79.1nslookup www.watt-intelligence.com 8.8.8.820d16cfa170e201c.vercel-dns-017.com216.198.79.6564.29.17.65The results are consistent across different DNS resolvers.
Connectivity Tests (India)
Ping succeeds for both domains.
ping watt-intelligence.com0% packet lossping www.watt-intelligence.com0% packet lossTraceroute successfully reaches the destination.
tracert watt-intelligence.com...216.198.79.1Trace complete.tracert www.watt-intelligence.com...216.198.79.65Trace complete.Intermediate hops timing out appears to be normal, as the destination is reached successfully.
SSL
The SSL certificate is valid.
HTTPS works normally from India.
What we've already ruled out
-
Incorrect DNS configuration
-
SSL certificate issues
-
Deployment failures
-
Application code
-
DNS propagation (issue has persisted for over two weeks)
Current Behaviour
| Location | Custom Domain | Deployment URL |
|---|---|---|
| India | ✅ Works | ✅ Works |
| Oman | ❌ ERR_TIMED_OUT | ✅ Works |
Since the deployment URL is reachable from Oman while only the custom domain times out, it doesn't appear to be an application issue.
Additional Context
A few weeks ago, Vercel recommended updating the apex A record from 76.76.21.21 to 216.198.79.1 as part of infrastructure changes. The DNS was updated accordingly, and the domain works correctly from India.
Could this issue be related to regional routing, edge network selection, Anycast routing, or another networking issue affecting custom domains from Oman?
Request
Could someone from the networking or edge infrastructure team help investigate whether requests from Oman to this custom domain are being routed differently from the default vercel.app deployment?
If there are any additional diagnostics, request IDs, logs, or headers that would help, I'd be happy to provide them.
Thank you.
