Some sites not accessible

Hello - We have implemented Magic Transit for DDoS protection for a subnet (prefix) advertised and is behind the Cloudflare. Hosts from this subnet can access certain sites, but some sites are not reachable and times out.

But some other works fine, like following has no issue.
https://www.nlm.nih.gov
https://cnn.com

Strangely we are not able to identify the issue. I will appreciate if any one has similar situation or guide us.

Thanks!

Hi there,
We’re sorry to read that you’re experiencing difficulties.

Since you are using magic transit, I believe you should have Premium plan.
We would recommend you to submit ticket from your dashboard regarding your MT issue so that our relevant team can help on your issue further immediately.

Please check this link to understand how to submit ticket from your dashboard: Contacting Cloudflare Support · Cloudflare Support docs

Best regards,

Hello Yuri1,
I appreciate your suggestion.

Yes, we do have Premium support and had submit couple of tickets on the dashboard. unfortunately there seems to be no resolution. The reason to post here was to seek any guidance from the community.

Thank you!
