Hi, Regarding sagenb.org, the "problem" is simply that too many people are using it. Over 500 right now.
I'll restart it, hence temporarily kicking everybody off. I will also adjust some limits on mod.math, so more file descriptors can be allocated. Obviously none of that is a longterm solution. Re-architecting the notebook server as we've discussed before (with a more scalable database-centric design) is. Your work on the single cell server is very important for this.
