Hi @jroberts, I don't know if these logs would be useful. But whilst waiting for my gaming PC to download a fresh copy of X-Plane 11 I fired up a windows VM on my work machine, VPN'ed it into our San Jose, USA head end and started that machine downloading a copy also.
Whilst the VPN machine was very constrained in terms of throughput, you'll see a major difference in the logs, not a single "E/INS" message in there, compared to the gaming PC that was appearing from a UK based IP address, which had countless of them.
XP11 Installer Log - UK IP Address
XP11 Installer Log - USA IP Address
I also find it interesting that the installer is still pulling v11.05r2 meaning that the first thing that happens when you run X-Plane if you get sent back to the updater to get 11.25r2. But that's a different question really ;-)
