Some customers may be experiencing issues this morning. This is due to BT issues in the south of England (Our data centres use both BT and Virgin so are still accessible, however reverse connections and access to instances may be effected if BT is your ISP).
Unfortunately this is somewhat outside of our control, however we may still be able to assist by changing your Authentication type, so please contact firstname.lastname@example.org if you are effected.
Some BT Broadband customers have reported problems accessing websites this morning. Sorry, we're aware of a problem & working to fix asap
