Extremely high packet loss
Since yesterday afternoon, we have been experiencing a very high percentage of packet loss within the Cloudflare network.
Here is an MTR trace from my Enscale env:

->Can someone investigate a potential issue with Cloudflare’s Manchester infrastructure?
->Cloudflare engineers, please run an MTR trace to the public IP I’m providing: 109.109.136.31.

thanks for replying.
Yes I still have problems...many.
the problem is limited to Cloudflare's reference infrastructure for Manchester.
In fact even from my network from Milan I have no problems....
