Hi,

I've just noticed something.... strange? I manage this mirror: https://archlinux.org/mirrors/librelabucm.org/ And I've just noticed that this other mirror: https://archlinux.org/mirrors/mirrors.marquitos.space/ Is actually just a reverse proxy to ours.

We are sure about this: * If I temporarily create a file in our mirror folder, it is also shown on their end, instantly * Every time I go to "https://mirrors.marquitos.space/archlinux/", I see in our server logs a request coming from the same IP as the one "mirrors.marquitos.space http://mirrors.marquitos.space" resolves to.

We've seen that aprox 1/10 of the requests we are receiving in our mirror come from this IP. I've added a temporary rule to enable their IP in our firewall, so they are not blocked, so if someone is using their mirror, it's still working.

I found his email address online, so I'm going to send him an email to ask him about it.

So..... * Was there any official request to add that mirror to the list? https://archlinux.org/mirrorlist/all/ * Is there any reason/benefit to offering a mirror as a reverse proxy to other mirror?      (I've checked, they are not caching files)

Thank you, Pablo

Hi, Seems there was an official request which was completed: https://bugs.archlinux.org/task/77618. Sometimes it happens that T2 mirrors sync from other T2 mirrors which is not really up to the idea of a tier-ing scheme and can show slower update times and this reverse proxying is peculiar (usually you use rsync for that) From my personal perspective I don't see any benefits as it can cause more issues since there are two parties involved especially when the other is not aware of it. Also if the mirrors are not geographically close to each other it can increase latency for the user without them knowing why. Best regards, Arun Arch Mirror team

Hi Pablo, I suspect most users will have multiple mirrors configured, and so would not be significantly affected by the other mirror going offline as a result of a potential block. Mirroring from a tier 2 is generally seen as poor form, and even more so when sending all the live traffic over. To answer your second question, there's little benefit to doing this from an official mirror, especially without caching. Back a few years ago when I was playing around with this sort of thing, I did find a speed benefit for distant users over connecting directly to the server, but there was extra latency in starting the connection. In an area already served by other high-quality mirrors, there's no real benefit. Regards, Tyler On Sat, May 20, 2023, 05:50 DevPGSV wrote:
