hi all,

As announced some months ago, majority of (centralized and sponsored by Red Hat) CentOS infra has to move from current DC (RDU2 - aka "Community Cage") to RDU3. That's where our friends (and colleagues) from Fedora recently migrated to some months ago.

It's so now our turn and we worked with DC/Network team[s] to have all ready and be in a position where we'd be able to move/migrate all services from one DC to the other. Some services are already migrated and running from new DC (or from the Cloud), but we haven't announced these changes, as it had no impact in the way you (SIGs developers) are interacting with these services.

For example, the whole CentOS CI infra (all components) are now running exclusively from AWS (special note : we'll have from new DC a tunnel to offer - as it was in the past - some ppc64le instances for duffy). Same for our MQTT broker and some other services (running now from RDU3) We already started to replicate our storage used in RDU2 to RDU3 (mainly for koji share volume for cbs.centos.org) and it's all on track.

We'll though announce in the next days/weeks some changes like : - lookaside cache server migration (https://src.sigs.centos.org/) - https://lists.centos.org mailman3 server (https//lists.stg.centos.org test instance is already running from new DC) - https://cbs.centos.org

Worth knowing that for CBS, we'll shift more to hybrid cloud model, so we'll have some "on prem" machines, but we'll also extend to AWS (for x86_64 and aarch64) for compute capacity. Also good to know that we collaborated with Fedora (running from same DC but different VLANs) to share some IBM Power 10 , so once migrated koji builders for ppc64le will be running on Power 10 (instead of Power 9). There is also a (pending) ticket about adding native risc-v builders to cbs, mainly to bootstrap publicly centos stream 10 but then available also for SIGs/community members (once there will be something usage), so adding another arch on our koji build infra (so we'll be supporting x86_64, aarch64, ppc64le, s390x and risc-v)

So stay tuned for more information to come about each of these services in the following days.
