Does NOW's broadband technical checks page at https://account.nowtv.com/check-service-status/ work for you?
All I get is a page saying "Hmm, that didn't go to plan. Sorry, we can't check your service at the moment. Please try again soon."

Assuming its the same as the ‘Test your line’ section here. Then yes.
