Hi Andreas,

let me summarize the details from my memory. The details are covered in [1].

- Automatic Updates is enabled in all packages since Eclipse Mars M5.

- There are not a lot of options available which is why we choose a weekly search on Tuesday, 10am. This day and that time has some advantages: It is not the first day after a weekend when everyone starts to work, and it is not too long after our usual release days (Friday).

- The search for updates starts at 10am *local* time or at the first time after a Tuesday, 10am when Eclipse is being started. Whatever comes first. In the worst case, all requests are spread in 24 hours.

- The download from eclipse.org should be limited to something like content.jar and artifacts.jar, the artifacts itself are loaded from the mirrors, and even those two files are cached and use xz compression whenever possible.

Hi all,

when testing the Neon M2 EPP packages, I noticed that Eclipse now
Automatic Updates enabled in the preferences. However, I wonder how the
update schedule is chosen. If everyone hits the foundation's servers at
Tuesday, 10:00 AM (the value it uses on all my Neon M2 installs), we
should see some traffic spikes (even though 10:00 AM probably refers to
local time, not UTC). Is this intended?

Best wishes,

Andreas
