I have taken a connection in Madurai, and they have assigned me a Chennai server as the WAN gateway. Usually the ping is 14-15ms to Chennai, but sometimes it goes to like 27-30 and stays like that for a day or two. Tried contacting ACT but they tell me to get a static IP. I tried explaining them that it's their gateway server(next hop after router local gateway) but they don't seem to understand. How should I proceed?
