    On a whim I decided to flush my DNS cache, and since doing so everything is fine.  I had tried Google's DNS servers and was still having the problem, so I didn't think flushing the DNS cache would make any difference, but I guess it did.  

     

    I did notice, while using Firefox, that the TLS handshake was the most prominent thing showing during the process of a web page opening, which I could see on the lower left of the page.  From discussion with Corrosive, I understand that Firefox basically takes a longer time to try to open a web page before it gives up, and this may be why Firefox was not messing up like the other three.  It would take a while to open the page sometimes, and, as mentioned, I could see that it was performing a TLS handshake during these delays.  I guess the other three would give up too quickly.  

     

    I'll keep an eye on it (it'll be kind of hard not to) and will post again when I know for sure whether the problem is solved or not.  

     

    Thanks again for the help.

Hi Gabe,

 

Thanks for all the details. Does clearing the browser cache make a difference? If the site fails to load, try loading it via a non-HN connection, like on your cellphone, does that work?

 

We can also check if we're getting similar reports, and if so, hopefully we can find a trend. Otherwise, I haven't seen the same behavior on this end.

 

Your cooperation, patience, and understanding are much appreciated.

      I think I can say conclusively that the issue has been resolved.  Whether by flusing the DNS cache or coincidence, I've not had one issue since doing so.  It's working perfectly now.

        DNS values are stored in several places:

        The Modem, The Router and the OS.

        Powering off the Modem will dump that one, powering off the Router will dump that one as well.

        Opening a command prompt and doing a ipcong/flushdns will dump the OS values.

         

        Cleaning out all the dust bunnies is the only sure way.
