Hi , @Smallship
Let me explain this , though its a long post please try to read with patience and also i worked with Major ISP. & closely worked with top broadband providers with India and had a decent understanding on the infra , technologies deployed by the ISP's in their core backbone
Problem : Your concern of High latency to Gateway of ACT
Generally Broadband Providers has a concept of PPPOE SERVER , which is technically called as BNG / BRAS this is where a virtual connection will be established from your home router to this server
BNG are very costly in nature , appx 1CR and above so ISP primarily choose to install these server only in Tier 1 / 2 Cities and get the Tier 3 Cities connected with Tier 1 / 2
so to explain this easier , your connection Gateway is in Chennai
Latency Issue : Latency is basically the distance between two hops which you were aware clearly by now
Why its jumping is the question ? Madurai to Chennai you will be having 3 Paths [ Path 1 , Path 2 , Path 3 ] , in this the telco primarily have lesser latency on the direct path , in case of outages on direct Path fiber cut , degradation the circuit travels on longer distance path which increases the latency
Impact of service ; Yes in todays point of view if you are playing a sort of High reliable gaming or something then 30ms may cause disturbance but when it comes to a normal browsing or watching netflix the Quality of service still remains as normal , as <70ms will be too good for a normal browsing ,
Now have a clean discussion with your Provider technical team & i hope for your sake the architecture of broadband cant be changed as it involves high opex cost
hope i have given you a clear explanation
