Traffic redirected from FAU mirror

[Joshua Root]

Just a heads up that most MacPorts mirrors will likely experience 
increased traffic in the short term, because we have temporarily removed 
the primary FAU mirror from our config due to excessive HTTP errors.

The ticket tracking this issue is here: 
<https://trac.macports.org/ticket/68563>

We will work with the FAU admins to try to resolve this as quickly as 
possible.
