Hi

State of the CI
- Somewhere along the axis of Ubuntu 17.10 - KVM we're hitting a SNAFU in a cycle of about 2 weeks. After that the virtual machines done on our hosts start slowing down enormously. We're working on replacing 17.10 with 18.04, but the work has been slowed down by us giving CPR to the current setup. We now have good redeploy scripts so that us redeploying these hosts weekly doesn't slow us down much.

Update of openNebula, MAAS & the build hosts
- Scripts have been updated and we have a working MAAS and openNebula. The host deployment to 18.04 is our current issue and we're working on figuring out how to deploy those.

- Coin is constantly running out of disk space, and with the current setup we are lacking redundancy of the hardware. We're planning to expand and / or move the storage to the Compellent storage. This enables us to start using standard rack servers for running Coin, thus giving us the redundancy we want, as any of the current build servers works as backup.

Rest of the infra:
- A new firewall has arrived. We've begun the swap over to the new one. Current cable connections documented and cluster preconfigured off site. When completed, it will be sent on site and connected to racks.
- We have one more infra server (the backup one I mentioned in the previous mail) taking off load of the 3 running ones. This shouldn't affect you at all. Mostly we hope to keep the loads more balanced so that in peak infra usages we don't run out of capacity. Shouldn't affect the CI at all.
- All public IP addresses in use. Andrew L. configuring new IRC server  which is going to be using the old one. We need maintenance break for  it when taking it into a production.

-Tony
