No. Hostmy1stweb uses a local key licensing system with periodic remote verification checks. What this means is that once every 5 days, your Addon Module will contact our server to ensure it is being run in the correct location and that the license is still valid. Your Addon Module being online is not dependant on our server being online during the time the local key is valid.
Should our licensing server not be online the day your next verification check is due then the system will allow up to 5 days for a connection to be made. If after this time, the system is still unable to verify your license with our licensing server then your Addon Module will become inactive until it can contact our server again.
Your additional addon's will always remains online even if you have an invalid or expired license to ensure module access is not interrupted.
