I’ve recently started using google‘s hangouts meet for VOIP video calls, which runs very smoothly 99% of the time. Every 5 or 6 minutes however there is a lag spike that will bring the latency temporarily to 200 ms or more, then it will drop back down to normal within a few seconds. This seems to be a regular thing that is happening.
I ran ping plotter to the hangouts meet front end media server (which Google recommends to use for troubleshooting) during a hangouts meet call and it reflected what I saw. There was never any packet loss, but there were always lag spikes every few minutes. I then used ping plotter on various IP addresses at once and it always had these lag spikes
I have the T3200M on TELUS purefibre 50/50 in Vancouver. My internet speedtests from speedtest.net are usually 60 down and 50 up. This testing is on 5 GHz Wi-Fi.
Hangouts meet support recommends to ping/trace route this address for troubleshooting: lens.l.google.com
Quick update: Interestingly enough, G Suite just emailed me saying there is currently a service disruption with hangouts meet, the very service I talked about. Trace routing that IP address I provided might give abnormal results due to this service disruption. What an interesting coincidence...
