 > I guess it needs a good trim then? (ie option 1)

 Having MacPorts ping fewer servers at once seems like it would help. I
 don't know what the best way to do that is though. Manually trimming the
 list in mirror_sites.tcl is one option but leaves open the question about
 how to decide which ones to remove, how many to remove, and how to ensure
 this any any other lists of sites doesn't grow too big in the future.
 That's why I favor a solution in MacPorts base, whether that's to check
 only a handful of servers each times MacPorts fetches a port's files until
 after a few ports all servers have been checked (seems doable), or limit
 the number of servers pinged at a time but check them all before fetching
 the first port's files (seems difficult, as Josh said, and could make the
 user wait longer than they expected for all the results to come in).
