Trying to order from Tesco and the Visa verification is failing to load - Fixed

[#1]

Thought it might be DNS again, so tried with Opendns and googles after a flushdns and still the same.  So any issues at PN towers affecting the online Visa security checker?

[#2]

are you trying with Firefox
reason for asking is that I get that problem on a few sites so switch to IE

[#3]

Opera so might be same issue as they share the same genes
edit used Waterfox and it worked, no idea why Opera is failing today as I order weekly and it worked last week same as it has for the last 2 years
