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
by FTP-Adminstrator 01 Apr '26

01 Apr '26

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?

Tier 1 rsync master access request — mirror.raiolanetworks.com
by Martin Gomez 04 Mar '26

04 Mar '26

Hello, We are Raiola Networks, a hosting provider based in Madrid, Spain. We have been running a public mirror for Fedora and EPEL for some time and are already registered in MirrorManager. We would like to request access to the Tier 1 master rsync modules (fedora-enchilada0 and fedora-epel0) on dl.fedoraproject.org. We are currently syncing from ftp-stud.hs-esslingen.de, but we would prefer to sync directly from the master to reduce lag and keep our mirror as up-to-date as possible. Mirror details: - Hostname: mirror.raiolanetworks.com - IPv4: 91.132.103.246 - IPv6: 2a12:d282:102:f6::1 - Location: Madrid, Spain - Bandwidth: 10 Gbps - Protocols: HTTPS, HTTP, rsync - Content: Fedora (fedora-enchilada) + EPEL (fedora-epel) - Sync frequency: hourly - URLs: https://mirror.raiolanetworks.com/fedora/ https://mirror.raiolanetworks.com/epel/ rsync://mirror.raiolanetworks.com/pub/fedora/ rsync://mirror.raiolanetworks.com/pub/epel/ Please let us know if you need any additional information.

Fedora & EPEL mirror
by Meir Kraushar 26 Feb '26

26 Feb '26

Hello mirror admin My name is Meir, I'm from ISOC-IL. We are an independent, non-profit organization, local chapter of the international Internet Society (ISOC). Our mission is to help with a reliable, secure, independent and fair internet for the benefit of all regional internet users. Among other activities we manage the .il country code top-level domain (ccTLD) registry, and the local internet exchange (IIX). Adding to the list of activities we also host mirror servers which provide repositories for the benefit of regional users, naming Almalinux, ArchLinux, RockyLinux, Ubuntu and so on. Our Peering with the local internet exchange is at 100G volume. Recently we've added new storage to provide additional repositories. As Fedora and Centos along with EPEL are extremely important, and since there are very few (if any) mirrors serving the region, we would be happy to contribute. Thanks in advance, it would be a big privilege to host your mirror. Sincerely, Meir Kraushar ISOC-IL

Persistently out of date mirror
by Thomas Klar 15 Feb '26

15 Feb '26

Hello Mirror Admins, I've just signed up to report this issue, which I've discovered last week, that one of the two mirrors in Switzerland is out of date and has been so for months. CERN has finally fixed their mirror, so it doesn't hurt that much any more, but the Init7 mirror has not been updated since November 2025: https://mirror.init7.net/fedora/fedora/linux/updates/43/Everything/x86_64/P… I've contacted them directly, asking them to either resume syncing or shut down their mirror, but they wouldn't even respond. Please remove them from the list, because for IPs from Switzerland, CERN and Init7 are the first 2 on the list being generated. If Init7 ends up being the first server contacted, updates are rendered inaccessible by their mirror being live, but out of date. Thank you in advance, Thomas

Please use a tier 1 mirror[1] close to you; create an account in the MirrorManager[2]; register your mirror in our MirrorManager; enter your local netblocks in the mirror manager and as soon as you are listed in the database as up to date yum/dnf will be redirected to your mirror. All this information can be found in more details in the wiki at: https://fedoraproject.org/wiki/Infrastructure/Mirroring Thanks for supporting Fedora. If you have any further questions do not hesitate to ask. It would help us a lot if you could provide rsync access for our crawler. Our crawler checks the content of your mirror and using rsync requires only one network connection in contrast to crawling via HTTP which can take up one connection per directory/file on your mirror.
