Periodic high latency and packet loss at intermediate hops
I have AT&T fiber and normally have extremely consistent internet (~8-900 mbps up/down, and 15ms latency). However, for the past week or so, I've noticed random periods throughout the day where everything seems to slow to a crawl.
I finally decided to perform some diagnostics and found that throughout the day the network was periodically experiencing extremely high latency and packet loss for around 5-15 minutes at a time, otherwise the network is pretty consistent. Over about a 12 hour span of time there 14 of these extremely high latency network events occurred.
Here is an image from ping plotter showing a 12 hour block with many of these "events" occuring:
Here is a 10 minute block from ping plotter that shows the state of the network closely during one of these episode:
Additionally, here is the output from a traceroute that's been running all night on my linux box that shows packet loss and an incredibly high latency standard deviation on one of the hops:
The latency and packet loss in each case seems to be introduced at an intermediate hop.
These periodic events nearly cripples any network usage while it lasts. Is there anything I can do personally to improve my network situation? Also, these hops seem pretty far away from my location, is this a widespread issue?
