Looks good to me but I let somebody from another VO have a look, because it may be of interest to them (maybe @iueda @hmiyake , as they have services scattered around the globe ? )

That's interesting. We are categorizing our servers to some groups (e.g. having UPS or not), then sometimes modify URLs to change active servers.

For such operation I prefer to change single value than list, since error proofing.

Let me gather comments to the PR from our colleagues.

At the moment this is on a per system basis, though maybe it would make sense to move globally for all URLs? Thoughts?

That's interesting. We are categorizing our servers to some groups (e.g. having UPS or not), then sometimes modify URLs to change active servers.

If it would be useful I could support a list of regexes, i.e.

    PreferredURLPatterns = .*\.preferred\.invalid/.*
    PreferredURLPatterns += .*\.secondary\.invalid/.*
    PreferredURLPatterns += .*\.tertiary\.invalid/.*

@hmiyake What would you prefer?

[hmiyake]

I wanted to ask the global option! For my user case, it completely matches.

A list of regexes are also helpful to give priority... I like both!
