Test results from last night: I did record an increase of latency around 6 PM last night but the increase was clearly being caused at Google’s router. My system and Cogent, our provider, were flawless. Pings increased from about 40 ms to google dns 8.8.8.8 and 8.8.4.4 to a high average of 57 ms. The ping times were still well with acceptable ranges. This is what a traceroute showed at 4 PM and at 8 PM but I have the data for every 30 seconds from 2 PM until the next morning: Sun 26 Nov 2023 04:00:47 PM MST traceroute to 8.8.4.4 (8.8.4.4), 30 hops max, 60 byte packets 1 _gateway (128.254.148.1) 1.445 ms 1.377 ms 1.350 ms 2 67.199.171.241 (67.199.171.241) 1.119 ms 3 * 4 be3110.ccr22.sfo01.atlas.cogentco.com (154.54.44.141) 18.154 ms 18.131 ms 18.109 ms 5 be3179.ccr22.sjc01.atlas.cogentco.com (154.54.43.150) 19.203 ms 19.182 ms 19.159 ms 6 be3177.ccr42.lax01.atlas.cogentco.com (154.54.40.145) 31.251 ms 31.306 ms 31.099 ms 7 be3359.ccr41.lax05.atlas.cogentco.com (154.54.3.70) 31.055 ms 31.216 ms 31.150 ms 8 tata.lax05.atlas.cogentco.com (154.54.11.194) 30.935 ms 30.831 ms 30.759 ms 9 * 10 142.250.164.40 (142.250.164.40) 41.429 ms 42.396 ms 41.336 ms 11 * 12 dns.google (8.8.4.4) 40.548 ms 40.520 ms 40.850 ms Sun 26 Nov 2023 08:00:05 PM MST traceroute to 8.8.4.4 (8.8.4.4), 30 hops max, 60 byte packets 1 _gateway (128.254.148.1) 1.408 ms 1.334 ms 1.489 ms 2 67.199.171.241 (67.199.171.241) 1.251 ms 3 * 4 be3110.ccr22.sfo01.atlas.cogentco.com (154.54.44.141) 18.119 ms 18.166 ms 18.070 ms 5 be3179.ccr22.sjc01.atlas.cogentco.com (154.54.43.150) 19.353 ms 19.332 ms 19.309 ms 6 be3177.ccr42.lax01.atlas.cogentco.com (154.54.40.145) 30.989 ms 31.266 ms 31.216 ms 7 be3359.ccr41.lax05.atlas.cogentco.com (154.54.3.70) 31.428 ms 31.398 ms 31.384 ms 8 tata.lax05.atlas.cogentco.com (154.54.11.194) 34.484 ms 30.943 ms 30.875 ms 9 * 10 142.250.164.40 (142.250.164.40) 57.770 ms 58.791 ms 57.842 ms 11 * 12 dns.google (8.8.4.4) 56.354 ms 57.645 ms 57.161 ms Notice the times were about the same on my router and through Cogent but increased when it hit 142.250.164.40 which according to ARIN is a Google address range. There was the occasional packet loss but didn’t appear to be significant. Loss is normal and was about what I would expect and was not likely caused in our network but I will test that further tonight. It doesn’t look like anything should have been having a significant impact on performance and our network was flawless. Are you seeing an actual performance decrease? I will do further testing and post the results. If anyone is interested in getting all the raw data just email me and I will send it. johnb@salemcity.org (assuming you are a Salem Fiber customer) Thanks, John Bowcut Director Salem Fiber 385-437-4411
