Hi,

I am using the Deutsche Telekom network with the public IP range 91.48.12.x/24, and I am experiencing problems accessing websites such as cloudflare.com, udemy.com, and linkedin.com. These websites respond extremely slowly.

On the other hand, websites that are not using Cloudflare CDNs work completely fine. Because of this, I suspect there may be an issue between Cloudflare and this IP pool. At the moment, I cannot even access Cloudflare’s own website, so I have to use VPN to reach it.

In the attachment, you will find ping test results that clearly show packet loss and very high round-trip times. I am unsure whom to report this issue to. Telekom claims that my internet connection is fine, which is partially true because apart from Cloudflare enabled websites, everything else (Facebook, YouTube, Hotmail, Gmail, etc.) works perfectly.

is anyone else is facing this problem and how to solve this problem?
