Thank you.

Then it was worth asking about this one.

You probably know who rr.com is, the target here.

Have you written anything to help us decide what target to use if we want to determine if we are having a problem with our ISP? I think I have read that that was the initial motivation to write Ping Plotter but I did not see anything with advice about what target to use. Of course you can't be too specific but everything I have seen has been too general.
