Unfortunately this mainly leads to bad connectivity as half of the
IPv6 world filters /48. Results are overly long AS_PATHs and really
ugly transit connections upteen times over the big ponds. Not in your
case as you can peer directly at DECIX and Space.Net's quite well
connected upstream Tiscali doesn't filter, but for other /48
wannabe-multihomers this looks MUCH worse.

Random example: http://www.sixxs.net/tools/grh/lg/?find=2001:418::/32

PA more-specific "multihoming" is _not_ a solution. If your link to
the PA-space providing ISP is down, you're unreachable from a lot
of sites. And routing problem debugging becomes a major pain.

Anyway, this isn't about DNS nameserver anycasting anymore, so... :-)
