How to Search Database Dead Zones by Date?
Our database has been around since 2001. However, we only have data from 2008-2015 on the map published as of today. You can now search the entire live database by date. See the example above.
In the future, we will be logging dead zones on a month-to-month basis and selling reports to carriers who want only recent problems. However, we all know that dead zones and coverage problems can persist for a long time and that is why continue to publish the data until a carrier can confirm that the problem has been fixed.
If you are interested in reporting coverage areas that have improved please read the previous link?
We also publish date-based heat maps of the coverage problems reported so you can see the reports evolve over time.
