Slight update, due to a phone hardware complication at WWV their phone number is not currently playing the science test signals. This situation may change moving forward. Due to the custom nature of the stations apparently simple problems don’t always have straight forward solutions. You can still call in to Colorado if you want to check that time is progressing linearly, but you won’t get to hear scheduled tones, chirps, and noise bursts on your phone. If unscheduled tones, chirps, and noise bursts are present on your phone please contact your service provider. If you want to hear science from WWV on 8 minutes past the hour you’ll need to do it over the air using receiver belonging to you or someone else.
