Faidon,
Ori correct me if I am wrong but analytics team has no instrumentation code
to measure performance. We store data that other teams produce.
In the case of navigation timing there are events storing the data on
EventLogging database for example:
https://meta.wikimedia.org/wiki/Schema:NavigationTiming
This data is been collected by the performance team and analyzed by Aaron
prior for other purposes, I think you should consult with Ori to see if it
would be suitable to measure what you are interested on, seems like if you
have a big enough dataset it would work.
Thanks,
Nuria

Hi folks,
As you've probably heard, last week we deployed ulsfo in production,
reducing latency for Oceania, East/Southeast Asia & US/Canada pacific/west
coast states. My estimation of the user base affected by this is 360
million users (as in, Internet users, not Wikipedia users).
I was wondering if you have an easy way to measure and plot the impact in
page load time, perhaps using Navigation Timing data?
The operations team has spent a considerable amount of time and money to
deploy ulsfo and I believe it'd be useful for us and the organization at
large to be able to quantify this effort.
The exact dates of the rollout by country/region codes can be found in
operations/dns' git history:

(the commits should be self-explanatory, but I'd be happy to clarify if
needed)
Thanks!
Faidon
