Note there is/was a PR for this, https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=200327. I don't understand our mirror structure, so I don't know if this change won't break some of them.
Would it be possible to change the 'max width' of the filenames in the auto-generated index?
In the names of the snapshots, the end of the filename is cut off, and this is important, as it is where the 'type' of image is (memstick vs dvd etc)
Do we generate that with some script, or is it auto-generated by the web server? If it's a script, it doesn't appear to be in htdocs.
It is auto-generated by the web server. Depending on the web server, you can adjust it with some configuration directives, but I am not sure what web server is used.
It seems work fine on all mirrors but not twn:
config is not propagated in that colo, @peter ,could you help to check this?
