Hello,

We are writing to inform you of a scheduled network maintenance window that may affect your hosted services at OSU Open Source Lab.

Time: 12:00 PM – 2:00 PM PDT (19:00 – 21:00 UTC)
Expected Impact: Brief outage (likely only a few minutes)

What’s happening:
LinkOregon will be enabling MLAG (Multi-Chassis Link Aggregation) on our upstream ports to our edge routers. Currently, all traffic flows through a single router. This change will allow us to fail over between two routers, providing improved redundancy and reliability for all hosted projects going forward.

We will also need to make some configuration changes on our routers ahead of the maintenance window. We do not anticipate these preliminary changes causing any disruption, but we will send a separate notification if that changes.

While we expect the actual outage to last only a few minutes, we have reserved the full 2-hour window as a precaution.

We apologize for any inconvenience this may cause. If you have any questions or concerns, please don’t hesitate to reach out.

Thank you for your patience and continued support of OSUOSL.

Thanks!

Short update on this (I need to run home).

I believe we have this mostly working. The only remaining issue seems to be that IPv6 with SLAAC isn’t working properly. We’re waiting to hear back from an Arista tech for a solution. I’ll send a more detailed message later once we figure everything out.

Thanks again for your patience and I apologize for the extended outage window.

Thanks-

We fixed the IPv6 SLAAC issue. I’m still working on the post-mortem and hope to have something sent later today or at least by tomorrow.

Thanks-
