Greetings. This data might be useful for tomorrow's Metrics WP call. In my proof-of-concept testbed, I am now collecting the SOA values that are coming in for the response latency tests. The output below shows the results of the five-minute gaps where not all the SOAs matched over a couple of days.

From the output, you can see that it is not always the same RSO that is lagging. None of the SOA transitions of the four so far took place in a single five-minute window.

Looking at the individual measurements, some collectors see different SOAs from the same RSO in the same collection period between v4 and v6; this could be routing differences, Some collectors see different SOAS from the same RSO in the same collection period between TCP and UDP; this is possibly due to load balancers and some of the systems behind them not being updated at the same time. FWIW, based on feedback from my earlier response latency numbers, I reduced the number of collectors to 8 instead of having multiple collectors in the same city. I hope this helps. --Paul Hoffman There are 213354 result recordss in the database Out of 513 five-minute gaps, 14 have more than one SOA 20190902:221502 (1567487702): a 2019090201: 14 2019090300: 20
