As far as I am concerned (and I maintain very huge mission critical systems), I'd treat your average small system for a tiny company in the same way. You have a small...

You know those films where it takes forever to kill the baddie? Those films where he (or she) keeps coming back despite apparently having been killed? That's what a GDSP (geographically dispersed...

This is far far worse than human error regarding a single event. It's not just one contractor. I hate to repeat that I have decades of experience in this form of computing. If I operated at my...

To be honest, you failed in your remit.

No. The UPS is more than a bank of batteries. It's an expensive piece of kit which smooths the supply during Brown outs, during spikes and during the absence of any power at all. The electrical input...

I've refused contracts where one particular outsourcer was involved. No names, obviously. The practice has been in the very large systems I've worked on to keep the crown jewels at home. Functions...

To IPL a mainframe shouldn't take more than five to ten minutes. If you want to cold start all systems and subsystems maybe a bit longer, but I'd expect to IPL my mainframe quicker than my smartphone.
