Hello, we see hugely increased latency from T-Mobile users to Cloudflare servers.
Example results:

This is from polish users T-Mobile connecting to polish server under Cloudflare. The ping for them should be max 30ms, while it’s 70-200ms.

I have the same problem, it happens between 18-22 GMT+2, i think it might be problem with tmobile’s relatively slow connection to internet exchanges outside of poland, they have about 400g in poland, but only 100g to decix, and their routers somehow route cloudflare traffic outside of poland, like they dont have a direct connection to polish cloudflare servers, and that 100g link may get overloaded. I hope they will sort it out quickly because it is getting quite annoying :smiley:

Unfortunately looks like me and users of my website are facing same issue. It’s trully frustrating

Have you found any solution? In our case it takes several minutes each to load from t-mobile Poland. Every other network loads in tens of milliseconds.

You should contact your isp to find out what issues they are experiencing issues.
