Title: Latency gone crazy
Post by: nivek1612 on August 18, 2017, 07:05:15 PM: This is weird I'm assuming there is a network contention issue somewhere to make the latency go like this since the early hours of this morning

Post by: Chrysalis on August 18, 2017, 11:21:18 PM: I can see the graph on my pc.

I dont think thats congestion, its consistent across the entire day.

If you absolutely sure its not your side (rebooted router's/modem and made sure no load), then try to report a fault for it.

Also do you have a ipv4 graph?

That was the feeling I had when I first viewed the data but, not being too familiar with such monitoring, hoped that someone more experienced in such analysis would comment. :)

Post by: Browni on August 18, 2017, 11:58:02 PM: The graph looks similar to the 2nd one here (https://www.thinkbroadband.com/faq/broadband-quality-monitor).

Post by: Chrysalis on August 19, 2017, 12:13:36 AM: That graph is missing, on my pc and phone.
Title: Re: Latency gone crazy
Post by: nivek1612 on August 19, 2017, 06:29:14 AM: Well both IPv4 and IPv6 graphs looked identical

This morning they appear to have returned to normal

Interestingly I discovered that there was an outage of The BT service in an adjacent area to me

So now suspecting some routing issues introduced by the outage
