We've now resolved the incident. Thanks for your patience.
We've fixed the core issue, and are waiting for things to recover.
We have identified an issue with the server where your PPS database is stored which, as a result, is currently preventing access to PPS.
Our team are currently investigating this problem and are working with our data centre in order to get all PPS services running as normal as soon as possible.
In the meantime, we apologise for any inconvenience this may cause.
