I am using Charter's 6rd IPv6 tunnel at home and noticed within the last
few days I can't get to/from my Digital Ocean VM via IPv6. From both
Digital Ocean and Charter 6rd tunnel I can get to Google, Facebook, etc
via IPv6 but not to each other.
It appears there are routing issues in GTT as it hits 64 hops and gives
up. I haven't found more examples.
