Probe every domain every minute, and keep it out of its own traffic numbers

NPM's access log only describes hosts somebody visited; the host most likely to be quietly broken
is the one nobody does. Probes carry a User-Agent npm_access_stats.sh drops — unmarked, this
monitor would be fifty thousand requests a day in the very logs it reports on.
