HTTP/3 super slow

Hi, today May 23, 2023 at 23:50, I’m experiencing super slow CDN transfers over HTTP/3 in Argentina, presumably from EZE datacenter. I’ve disabled HTTP/3 from the dashboard and issue disappeared over HTTP/2!

Any clues?

Cloudflare status page shows that EZE is re-routed. However, I wonder why HTTP/2 traffic is fine whereas /3 doesn’t?
