I favoured an Apache host as it meant others could collaborate more easily, but I believe justifying a second host would have taken time and may not have been approved. I think our current approach was reasonably balanced given the risk to the demo sites vs benefit of experimenting with new approaches, (perceived) impact on users and how rapidly we addressed issues as they were discovered. We hit this RAM issue twice. The first time it occured we recovered quickly and implemented some mitigations to constrain resource usage by the containers. What we didn't think of was that RAM usage would increase again during the nightly build, making the VM unresponsive again. However in response to the first occurrence we already had a request out to INFRA for a RAM uplift which was already approved and was just waiting for a suitable time for application. (Note: I am still assuming the issue was lack of memory. We don't have any metrics yet to confirm this) I don't have any figures on how much traffic our demo sites get, but I have a feeling it is low. Given how quickly we addressed the problems I don't think there was much impact to users. It would be good to have some metrics on demo site usage though. It could be something we include in the PMC report/blog post as an indicator on user engagement with the project. Dan
