It's possibly not showing up there yet because it's more localised and not a wider area outage.
You could also try the Service Status number 0800 561 0061. This often gives details of more local issues down to postcode level, however it's not a manned line and it make take some time until it reaches your postcode area.
downdetector.co.uk isn't currently showing any major issues, which seems to confirm it's a small local outage.

Just to add a little to what newapollo has (rather well!) explained, a bit more of my understanding of localised faults that aren't picked up by the monitoring systems.
For the first few customers who call in affected, there won't be a recognised issue and so engineers will be booked. Once the number of tech visits in particular postcodes/cabinets with similar issues, reaches a trigger point, then a network fault is raised and tech visits potentially cancelled. At this stage it should be reported on the local status line 0800 5610061.
I'm not sure what the triggers are for that to happen, but it sounds like your area has met the criteria
