These need configurable.  There are a lot of wisps that would have everything orange/red.  We're considering anything under 100ms good on the rural plans.   Also keep in mind that if you're tracking latence via pping etc, then you need some buffer in there for the internet at large.  <70ms to Amazon is one thing, they're very well connected, but <70ms to most of the internet isn't probably very realistic and would make most charts look like poop.
