They’re playing the statistical probabilities just like anyone else stocking their own spares pool. The biggest difference is that they’re spreading the risk across a (potentially) much wider sample size which may better normalize the numbers.Yes, it's just like a bank - they hope not all customers come to withdraw all their cash on the same morning.
Yep… FWIW, my experiences were in locations in the US with NFL teams and multiple depots proximate to each location. That didn’t help in these cases.
We run a CRS 4-port 100Gbps line card that I know is not very popular among other operators in the markets where we have them. We had one fail in a smaller city a few weeks ago. We pay for NBD, not 24/7. A new line card arrived promptly, the morning after. I did hold my breath, but they managed.
Yeah, that’s far less likely to be a problem than a popular line card or other component that turns out to have a bad batch. Generally, they’ll keep at least one of everything any customer has in at least one nearby depot. OTOH, I bet if you’d had two of those cards fail, you might have been SOL on the second one for a couple of days. Owen
