I have a site with a 2860 installed where there has been a 3/4/5G dongle installed for years for use as a failover connection should the main connection fail.
Suddenly I am getting emails from Three to alert me to the fact that data usage has gone through the roof with more usage in a day then previously occurred in months. The Draytek interface however does not seem to show any real usage of the 4G connection and the FTTC connection does not seem to be having any problems to cause a failover. The Three billing website does not appear to be working properly and I cannot get daily usage figures from them at the moment as I have done previously. I suspect a fault with Three's systems.Does anyone else use Three for a backup connection. If so are there any problems? I have temporarily disconnected the dongle.
