Just to let you know I was on the point of clicking to submit a vat return online when the HMRC VAT servers crashed. The reason I say this is that none of the links to vat pages work either. The maintenance page to find out what's wrong doesn't work either. No pages concerning vat work at all. A total crash around 11:25 this morning.
Half an hour later at around 11:55 I have access again so I am trying it now.
All working again. The service pages don't mention this temporary loss of service.
