I had confirmation yesterday that it was NOT my cable modem as I first thought. No indeed; it was a problem with service I was using for my “free” blog, in general within Canada and Holland.
I can now access my old blog from home.
It was a good reminder of how fragile it is to have a “free” service. I’m glad I made the move to a dedicated domain and paid-for hosting service. Particularly since I could import the content from my old blog.
It’s the small things that count.
