I have in the past suggested that we consider hosting services at
diverse places. I'd have thought this was a prima facie case for
distributed hosting facilities. If we have that, we have no need for
mirrors, but instead for systems management. I know of at least three
reputable US hosting companies who I am pretty sure would help, and a
major academic hosting organization too. Also maybe Snakebite might be
another location?

This is an infrastructure committee task really. Brett? Martin?

Brett: maybe your closing report to the board could summarize the
overall hosting situation?
