As well as trying the “check service,” Area status webpage" (link at top right of this forum), there is also a Service Status number - 0800 561 0061 - which usually tells you of more local issues down to postcode level (that may not be listed on the Area Status web page which usually covers 1000’s of customers) - that may give you more info, but even that wont cover problems affecting just a few customers.
