I apologize I think this question is in the wrong forum, so....
How can I tell if the DSL/CABLE/... connection to my home is generally working?
Right now, the various broadband speed tests all show a very reasonable (for the US) latency of about 40ms, with a download speed of 15Kb/s.
And yet, as I surf CNN, Amazon, Office Max, and various other sites this afternoon, I notice that many of the images, but not all, are broken, and the big wheel in the tab keeps on spinning indicating connections that are still downloading, slowly, and not completing.
What tools do you use, and what attributes do you look for to conclude Internet connectivity to your site is generally good?
