I've been using smokeping to monitor internet latency (for early problem detection) at 188.8.131.52 for several months. On Friday the average latency went from 12ms to 55ms and has been at the 55ms plateau for 3 days. Our WAN uses the same provider for all internet connections so we're curious as to whether they have a problem or if 184.108.40.206 just decided to choke the pipe down.
Our ISP claims the problem is at 220.127.116.11, but I am still suspicious.
I notice I get the same (55ms) latency to 18.104.22.168, but I wasn't graphing that IP so I don't have any reference data to prove a degradation in service.
Any recommendations on how to pursue this anomaly would be helpful.
PS: Flow shows no excessive traffic on our routers that would point to a behavior-driven drop in service.
