404 Error for https://www.w3.org/2005/05/xmlmime via Cloudflare MXP node (Italy)

Dear W3C Site Team,
I am reporting a persistent 404 Not Found error when trying to access the following resource: https://www.w3.org/2005/05/xmlmime
The issue seems to be related to the Cloudflare edge node in Milan (MXP). Users connecting from TIM (Telecom Italia) are consistently receiving a 404, while the resource appears to be available from other Italian ISPs (like Vodafone) or via foreign proxies.
Here is the technical output from a curl command executed from the affected network:
> HEAD /2005/05/xmlmime HTTP/1.1
> Host: www.w3.org
> User-Agent: curl/8.13.0
> Accept: */*

< HTTP/1.1 404 Not Found
< Date: Thu, 22 Jan 2026 22:12:53 GMT
< CF-RAY: 9c2265370b136c5d-MXP
< x-backend: www-mirrors
< CF-Cache-Status: BYPASS
< Server: cloudflare

Key details:

  *
Resource: https://www.w3.org/2005/05/xmlmime

  *
Edge Location: MXP (Milan, Italy)
  *
Status: 404 Not Found (with CF-Cache-Status: BYPASS)
  *
Affected ISP: TIM (AS1267)

It appears the MXP node is unable to correctly fetch the resource from the origin or is receiving a 404 from the www-mirrors backend for requests originating from specific IP ranges.
Could you please trigger a cache purge or verify the synchronization of the Milan edge node with your origin servers?
Best regards,
Federico Nanut
