Dear Wikimedia Foundation Inc.,
Action Required
We kindly request your prompt attention to update your network configurations with the new IPv6 addresses provided below. This action is essential to ensure seamless connectivity and continued access to Arelion's services.
Background
The IPv6 addresses currently in use for below services were assigned by Arelion's former owner, Telia Company. As a result of the separation, we need to transition your services to use new addresses owned and managed by Arelion. To ensure minimal disruption to your operations, we have preconfigured the new IPv6 addresses in parallel with existing on our routers and replicated the settings of your current BGP sessions. The transition process has been carefully planned to maintain service continuity while aligning with our network policies.
Technical Details
All the new linknet IPs and BGP sessions are configured in parallel with existing on Arelion side. Change should be possible without interruption, at any time, by adding the new IPs and session(s) before removing existing config on customer side.
Please note that only the IPv6 addresses and BGP neighbor session will change. All other BGP related configuration will remain the same. E.g., if you have BGP configured with MD5 authentication today, the same key should be used for the new neighbor session. Arelion's will still be using AS 1299.
Deadline for Reconfiguration: 2024-10-31
To facilitate a smooth transition, we have established a deadline for the reconfiguration process. We urge you to complete the update before the end of October this year to avoid any interruptions in your IPv6 service.
Please be advised that following the deadline, the configuration for the old IPv6 addresses will be removed from our systems. Failure to update your network configurations with the new IPv6 linknet addresses before the deadline may result in service disruptions.

Support
Should you require any assistance or encounter challenges during the reconfiguration process, our support team is available to provide guidance and support. You can reach the migration team directly at ipv6-migration@arelion.com.
We sincerely appreciate your cooperation and understanding in this matter. Your prompt action is vital in ensuring a seamless transition to the new IPv6 addresses. Thank you for your continued partnership, and we remain committed to delivering exceptional service.
Service IDs are on the IPs' PTR and show up in traceroutes so no need to hide them.
We need to update Homer ( https://gerrit.wikimedia.org/r/c/operations/homer/public/+/1035376) and Netbox
