Please review VPC Peering and AWS PrivateLink for updates about the pricing plans and CIDR block. If you could ask someone to do a quick validation of the procedure please. A customer said that they had issues: https://docs-dev.timescale.com/docs-3478-content-bug-documentation-on-vpc-peering-configuration-needs-updating-as-it-was-not-accurate-for-their-setup/use-timescale/3478-content-bug-documentation-on-vpc-peering-configuration-needs-updating-as-it-was-not-accurate-for-their-setup/vpc/

Hello @miqrc, @esclymeTS , just double-checking before I publish. I had another ticket (#3478) saying that they had issues with the VPC procedure. Did you have time to check that the procedure is correct?

@billy-the-fish I reviewed the doc, and everything seems okay.
I don't know if it's the issue you refer to, but there was a bug in the code that is already fixed but doesn't affect the procedure.
Also, some users want to peer from GCP/Azure, but that's another story.
