While on my Hurricane Electric IPv6 tunnel, I cannot access juniper.net unless I change my local interface MTU. 1500 fails, but 1280 works. I noticed this a few days ago. Before that I had no problems with a 1500 MTU. Is anyone else seeing this issue?

No, but if your are using a 6in4 tunnel, the MTU should be 1480 (not 1500). (I just successfully went to www.juniper.net via IPv6 with that MTU 1480.)
