Nope.
We've had two minor issues - one case of broken PMTUD, which was
affecting users whose IPv6 is tunnelled (unmanaged or managed). We (or
rather, I - my colleagues should remain blameless) did a vile hack and
used MSS clamping to fix it, because the system in question is hard to
fix properly on short notice.
The other was some weirdness in our load-balancer related to v6->v4
translation, which we've just fixed.
Both are site-specific and not indicative of general problems.
FWIW, now that BBC has gone over, we're pulling a truly startling
60mbit/sec of IPv6 traffic. Gulp! A new record for us!
(Though it does rather pale in comparison to the 2.8Gbit/sec that our
High Energy Physics lot are currently shifting...)
