We are aware one of our upstream providers is suffering a network issue affecting a small number of 020 prefixed inbound calls routed via them.
This issue has been raised with the respective team and they are dealing with it as a priority.
We apologies for any inconvenience caused and will continue to follow this up with them posting updates as they become available.
UPDATE 01 – 11:45
We are starting to see inbound calls connect again from the affected 020 numbers. We have not been officially advised this has been resolved but services from this carrier are starting to restore.
