Have you used the /check-services/i function? You can also a run a test on your equipment from there.
If nothing is showing you could also try the automated Service Status number 0800 561 0061. This often gives details of more local issues down to postcode level.
Welcome back to the community
Sorry to hear that you were experiencing service issues on Sunday. I have checked the systems at our side and can see that there is no longer an area outage raised for you.
Please do let us know if you have any further issues at all, we'll be here to help on the community forums if needed :).
