I am noticing far worse performance and reliability with IPv6 as opposed 
to IPv4.  For a good 10 minutes until just now there was *no* IPv6 routing 
even to the first hop, but IPv4 was still "working."  Now things are 
merely slow, not broken.

I also got bounced a few times from -secure and -a and when I got back I 
couldn't get an address (IPv4 or IPv6) for some time.

Conjecturbation: They're using an old proteon router and someone is 
exhausting its arp and ndp caches.
