Mother’s Day

There is a great anecdote in the book “Eccentric Orbits – The Iridium Story” that I reviewed in a previous post.

It was May 9, 2004. The technicians at the Network Operating Centres for the Iridium satellite system in Hawaii and Arizona noticed a high level of dropped calls (more precisely failure to connect) and a very high level of traffic in general. They were confused because everything seemed to be working normal, and the system could hand almost 100,000 calls at a time and there were barely 140,000 handsets in service at the time.

Then they noticed that all the calls were coming from one particular place, massive numbers of people were all trying to call over the same satellite. That is what was taxing the system, a specific geographic overload. You see, there were 146,000 American troops stationed in Iraq at the time. And that year, May 9 was Mother’s Day.

The only situation that could max out the Iridium system was Mother’s Day in a war zone.

Anyone who has spent time in network or traffic engineering for a telco knows that the busiest day on the network is Mother’s Day. Even more than Christmas, or any other holiday. That is why I laughed when I read that story as it immediately resonated with me. All these soldiers and Marines HAD to call home on Mother’s Day.

So make sure that your network is ready for this Sunday, because the traffic is going to ramp up bigly.

And don’t forget to call your Mother !
