cp1.miraheze.org is a cache proxy and NFS server for static.miraheze.org. cp1 has a lack of RAM (for puppet mostly) and disk space (for static content).
cp1 is currently on the 128MB CVZ plan ($15/year), with 80GB disk space, 128MB RAM, 1 CPU @ 2,30 GHz. The best upgrade is the 256MB CVZ plan ($8/qtr, so +$17/year), which gives us 256MB RAM (+128MB VSwap) and 120GB disk space.
At our current growth rate, cp1 will run out of disk space in November (and perhaps earlier, because the growth rate can increase). If the upgrade is done, we should be safe until March. [1]
