Hi Alex,
Thank you for the more detailed explanation on data packets for networks including GCP. That’s essentially my understanding, as far as just a basic outline on the topic.
As far as the reference feedback from the user forums or blog posts, I tried reviewing a bit earlier this week to find them and either no longer have them bookmarked or couldn’t easily locate them with a quick search. When I pull up the first link that you mentioned to the Network Intelligence Center dashboard, for my current project dev test, it results in the following screenshot:
Which seems to be in line with the impression I had, of 99.9% uptime, but this chart is indicating a very slight packet loss of 0.5% or less. What’s interesting is that this is on a 1 hour time scale, and right now I don’t have any infrastructure in this project (because I’d already “terraform destroyed” everything, in order to reset and conduct new tests).
It seems relatively insignificant, in light of the progress that has been made to ensure data preservation uptime, especially by GCP. At the same time, pairing two different virtual private networks together in a peering network, in order to link the different services, or GCP assets, over a longer timeline horizon, was the resulting question I had described before.
Interestingly, after considering your feedback this week, I did some extra research, and found one other GCP customer who tried testing his companies network on both PSA and PSC. His results suggest what you described, that PSC is newer, better, but also costs more than PSA:

In this above link, he comments the following:
“This is a common issue in the cloud market. For instance, Google was aware of the transitivity issues but has implemented all managed services behind an inaccessible unmanageable network, where peering was your only option. They then introduce a solution, but it requires paying more.”
By transitivity issues, was he describing the network peering and/or data preservation concerns? It’s unclear to me what exactly he’s referring to on that point.
Having said, that, through this conversation, I’ve arrived at the direction to take my project in going forward regarding these available GCP connection options, for which I’m certainly grateful.
Thanks, Tim
