Rate-limit the GeoIP list for the affected areas to drop if more than 20% of active traffic. i.e. the service outages get co-located only with the problem users areas.
Also, when doing auto-updates: always add a chaotic delay offset 1 to 180 minutes to distribute the traffic loads. Even in an office with 16 hosts or more this is recommended practice to prevent cheap routers hitting limits. Another interesting trend, is magnet/torrent being used for cryptographic-signed commercial package file distribution.
Free API keys are sometimes a necessary evil... as sometimes service abuse is not accidental.
