For the first time since the upgrade I appear to be able to access Ribnet as usual.
Can I please ask that 'The Content Delivery Network' whatever that is, is tested and tested again before it's turned back on again.
Strangely the Z1 Owners club forum I use has also had issues last night. The whole site has reverted back to where it was in March 2010 and everything since has been lost. We've even had to re-register, so compared to that Ribnet got away with it lightly.
