Opendns failing for me today

[#1]

Had to revert to PN's dns servers as 208.67.220.220/208.67.222.222 have been letting me down for last hour or more.

[#2]

I had that problem yesterday (I think - memory fails with age) so I changed to one Plusnet and one OpenDNS to cover both options

[#3]

There is an issue with BIND 9 at the moment whereby DoS attacks can crash servers. Maybe it's that.
