pkgin repositories

[Jason Bacon <outpaddling%yahoo.com@localhost>]

My current etc/pkgin/repositories.conf is as follows:

https://mirror1.hpc.uwm.edu/pkgsrc/packages/usr/pkg/RHEL7/All
https://mirror2.hpc.uwm.edu/pkgsrc/packages/usr/pkg/RHEL7/All

I've noticed a few times that if either server is down, pkgin operations 
like update or install will fail.

I would have thought that if one server is down, it would fail over to 
the next one, but it appears
they all have to be available.

Is this by design, and if so, for what reason?

Thanks,

    Jason
