Service Advisory

TL;DR:
I recently moved into a new house and my new ISP (Quantum Fiber) equipment/line delivery is not performing as expected. Services may be slow or briefly inconsistent. Sometime between Sunday (3/1) and Monday (3/2), I will take the connection down briefly to test an ONT-bypass approach.

What Changed

The new location is Quantum Fiber 8Gb service delivered over XGS-PON. They installed a Q1000K (SmartNID/ONT + gateway) and a Wi-Fi pod.

Right now, I’m seeing about ~3Gbps average throughput (instead of expected multi-gig performance) and intermittent disconnects, which makes services feel slow and inconsistent.

Likely Root Cause (High Level)

This does not appear to be an internal Lightmedia infrastructure issue (compute/storage/switching/routing are healthy). The symptoms point to the provider handoff layer (how the optical line is being terminated and presented to Ethernet), plus downstream negotiation/cabling considerations on the multi-gig path.

Planned Fix: ONT Bypass Test

To remove the ISP-supplied ONT/gateway as a variable, I’m testing a direct termination method using an SFP+ ONU module. This can eliminate an extra translation layer and may stabilize the link while restoring full throughput.

What this should improve:

• More consistent multi-gig throughput
• Reduced disconnects / session drops
• Cleaner diagnostics and monitoring
• Less reliance on ISP device behavior

Expected Impact (3/1–3/2)

During the maintenance window, you may notice:

• Short interruptions while the optical handoff is reconfigured
• Routing resets during validation
• Temporary service restarts

Once complete, this should resolve the current “half speed + instability” behavior.

No action is required on your end. If you see issues outside the 3/1–3/2 window, reply to this message and include the time it occurred.
