Subject Re: Modern template hosting
Date Fri, 03 Mar 2017 23:28:37 GMT
Yes Erik, I agree with you. The only thing that could add complexity in
this is the fact that we don't control the domain, the ASF does (from what
I understand).  Do we expect this to be managed by ASF infra or would there
be another way? Ideally the domain is community controlled so we can adapt
in case of change without long delays.

I am 100% in agreement that this is the shortest path and likely to be good
enough.

IMHO; implement it as simple as possible, use DNS RR and assume/expect
mirror hosts to use the same path.


Yes I know; DNS RR isn't bulletproof, but as already mentioned in this
thread - mirrors rarely go down and they aren't used all that often
(primarily seeding).
We can keep a low TTL on the record so that we're able to remove a
mirror that goes down for a significant period of time (more than
hours).

And yes I know, some operators might find it a burden having to set up
a new vhost with another document root, but tbh if they don't care
enough to do it we'll manage without that mirror.
