If you’ve been in the developer space for a while, you might recall a controversial move by Malaysia’s MCMC (Malaysian Communications and Multimedia Commission) some time ago — when they blocked access to the Bootstrap CDN just because a gambling site was using it. That decision caused widespread frustration among developers and regular users alike.

Unfortunately, history may be repeating itself.

Discovery: Community Alert

This issue was first spotted by Ahmad Saiful Bahri, who shared his findings on Facebook. He noticed that websites hosted under the .vercel.app domain were no longer accessible via the Maxis network.

His post raised concerns within the developer community, prompting others to verify the issue.

Confirmed: It’s Not Just Him

After reading Ahmad's post, I ran my own tests — and I encountered the same problem. Websites using .vercel.app subdomains failed to load, and pinging them returned this redirection: 
MCMC-redirect.maxis.com
ping and nslookup results to a .vercel.app domain
Terminal output showing ping and nslookup results to a .vercel.app domain being redirected to MCMC-redirect.maxis.com.
This proves that the block is enforced at the network level — likely via DNS poisoning or HTTP redirection configured by the ISP (Maxis).

What’s Actually Affected?

Domain TypeStatus
vercel.com Accessible
*.vercel.app Blocked on Maxis
Vercel custom domains Still accessible
Access via Celcom/Yes5G/Umobile/Time Fiber/Unifi (tested) No block detected

So far, only Maxis appears to enforce the block. Other ISPs, like Celcom, still allow .vercel.app domains.

Temporary Workarounds

If your app or a site you’re trying to access is blocked, here are your options:

1. Change your DNS to Cloudflare (1.1.1.1) or Google (8.8.8.8).
Config a DNS to bypass the BLOCK
Configure a DNS to bypass the BLOCK
2. Use a VPN to route your traffic through an unaffected network.
Connecting to a VPN node on Surfshark VPN
Connecting to a VPN node on Surfshark VPN
These methods should restore access, for now.

Why This Block Is a Problem

Blocking an entire platform domain like .vercel.app is an overkill response. Here’s why:
  • It disrupts innocent developers and businesses using Vercel’s default domain
  • It affects educational tools, portfolios, and community projects
  • It breaks trust in Malaysia’s tech ecosystem and digital governance

Just like with the Bootstrap CDN block, punishing an entire ecosystem due to a few bad actors is a clear case of poor enforcement strategy.

Final Thoughts

This incident highlights the urgent need for more granular and intelligent enforcement mechanisms. The current approach by MCMC (and enforced by Maxis) reflects a lack of understanding of how modern web infrastructure works.
