Episode notes
Initial Troubleshooting
- An Oxide customer had image upload issues only when uploading from within the rack.
- Uploads from outside the rack worked fine, adding to the puzzle.
Hairpinning Discovery
- The issue was isolated to inter-VPC traffic within the Oxide rack, which hairpins through external networks.
- This differs from external uploads, which don't hairpin.
VPC to VPC Traffic Flow
- Inter-VPC traffic exits the rack due to current Oxide architecture and customer security preferences.
- Customers often want security appliances to inspect traffic between tenants (silos).
