I'm a Sr Network/Internet Engineer (and Operator), ran a transit/access Internet Provider for 10 years. Nice to see other similar people here
Where I'm working now is more of an oversight/management role, and I've got a site in Toronto with a Halon system we need to get rid of. We're in a multi-tenant building, and if that halon system ever fired, the entire building would have to be evacuated.
I'm looking at about $1.5 million to get rid of it at that location and replace it. We've got a massive data centre and NOC right in the literal core of the building.
Happy growing!
