Persistent HTTP 520 Errors and Lack of Maintenance on mirror.krfoss.org
by paru paru 02 Apr '26

02 Apr '26

Hello, I am writing to formally report a long-standing issue with the mirror https://mirror.krfoss.org. Recently, while attempting to use this mirror for Fedora 43, I have been consistently encountering HTTP 520 (Origin Error) codes. This is not an isolated incident; this mirror has been frequently unstable and has produced similar errors for a long time. Furthermore, I have attempted to contact the krfoss.org maintainers directly regarding these issues in the past, but they either do not respond at all or are extremely slow to take action. This lack of maintenance is causing significant inconvenience to Fedora users in the region. Details of the issue: Mirror URL: https://mirror.krfoss.org/fedora/ Error Encountered: Persistent HTTP 520 (Origin Error) via Cloudflare. Problem: DNF cannot fetch packages reliably, and the mirror is unreachable. Context: This has been a recurring issue for a long time, and the local maintainer is unresponsive. Could the Fedora infrastructure team please look into the status of this mirror or consider taking appropriate action if it no longer meets Fedora's mirror standards? Best regards --- ```bash paru@moe:~$ sudo dnf install golang \ --disablerepo='*' \ --enablerepo=fedora \ --setopt=fedora.mirrorlist= \ --setopt=fedora.baseurl=https://mirror.krfoss.org/fedora/linux/releases/43/Everything/x86_64/os/ Updating and loading repositories: Repositories loaded.

poor transfer rates

Hello, We are a Tier 1 mirror provider, and for the past two weeks, we have been unable to successfully update our Fedora Enchilada mirror. Although we are connected via a 100 Gbit link, we have periodically encountered significant performance issues over the last few years. These include extremely poor download rates (averaging 300 kB/s), connection timeouts, "file not found" errors, and rejected connections due to reaching connection limits. In 2023, we switched to the co-located server download-ib01.fedoraproject.org, which resolved these issues for approximately two years. However, the problems resurfaced a year ago. We have observed consistently slow connections to all known Fedora upstream mirrors. Currently, the image synchronization takes several days, meaning fedora-quick-mirror never completes the package downloads, resulting in hours of wasted bandwidth and time. To mitigate this, we developed a wrapper script for rsync that intercepts the interaction between fedora-quick-mirror and the rsync process. This script splits the file list into chunks, allowing for parallel downloads from multiple mirrors and automatic retries on failure. While this workaround functioned for several months, the issues returned last month. We are currently attempting to sync 1,424,731 files/directories, but the process never finalizes because the image downloads do not complete. What can we do to resolve this issue? Is there a Tier 0 mirror in Europe which has better connectivity?
