Two weeks ago, I lost not one but two important calls to the internet going out (for a lot of good reasons, I use internet-based telephony primarily). Once was at an upscale cafe, where the internet had never died before. The other was in my business partner's wonderful large furnished high-end multiple-bedroom apartment that we use as HQ sometimes... where the internet had also never died before.
But, you see that "the internet had never died before"?
That's irrelevant. It's nonsense. It's an excuse. It's throwing your arms up and saying, "Well, what could I do? It just happened."
But you can always do something.
I got an unlimited data plan for my iPhone, and can tether it to my laptop now.
At the same time, I refuse to get on important calls on only the tethered phone, I want good internet wherever I'm at too.
2x connections. Pretty much unrelated to each other. No being at the mercy of internet outages anywhere.
No excuses. It's always your fault. Make a better backup plan.
