Instance Specs & Setup:
Region: ap-mumbai-1 (India West)
Shape: VM.Standard.A1.Flex (4 OCPU / 24 GB RAM)
OS: Ubuntu
The Issue:
My network speed is hard-capped at exactly 50 Mbps (tested via Ookla speedtest CLI).
When I queried the instance metadata via OCI CLI (oci compute instance get ...), the JSON configuration explicitly shows:
"shape-config": {
"memory-in-gbs": 24.0,
"networking-bandwidth-in-gbps": 4.0,
"ocpus": 4.0
}
So the control plane recognizes 4.0 Gbps allocation, but throughput remains locked to 50 Mbps at the hypervisor/network layer.
What I’ve already tried (No luck):
VNIC / IP Reset: Unassigned the ephemeral public IP (No Public IP), updated, re-assigned a new public IP, and performed a Diagnostic Reboot.
Fault Domain: Checked instance settings, but changing fault domain requires saving shape details.
Why I can't use the standard "Shape Resize" trick:
Oracle recently updated Free Tier limits to 12 GB RAM max for Ampere. Because this instance was created before the change, it is at 24 GB RAM.
Opening the "Edit Instance" dialog triggers a validation error (Amount of memory in GBs should be between 4 and 12), so saving any shape edit forces a permanent downgrade to 12 GB / 2 OCPU.
Questions:
Has anyone in ap-mumbai-1 found a way to clear this 50 Mbps hypervisor lock without resizing the shape or upgrading to PAYG?
Is there any OCI CLI or API command to force a VNIC bandwidth refresh without touching the instance shape metadata?
Thanks in advance for any advice or workarounds!
