A fuel supplier accidently puts half a load of jet fuel instead of #2 diesel in your storage tank, which you won't find until it reloads the run tank from the day tank.
Take samples from the fuel tank and test them every time tanks are filled.
Floods happen and the water rises taller than the 3 story snorkle on the diesels.
Don't site buildings where there have been floods in the past 500 years and don't site buildings downstream from dams. If a waterproof building is built in a flood area, make sure that snorkles rise above the 500 year flood level.
Generators takes a direct lightning strike and fries house DC power (even inside shielded enclosures). A fiber transmission system goes crazy when the control system is zapped by the lightning strike on the generator.
Is there any way to protect against lightning?
A 200mph hurricane gust rips a microwave system off the roof (tower and all) and throws it down on the generators, crushing the exhaust system and the diesels strangle. (No, I'm' not imagining these.)
When siting a diesel exhaust system make sure that there are no trees, towers or similar things nearby that could fall on it. If in a hurricane area, reinforce diesel snorkels and arrange for multiple paths to get air in.
We all try very, very hard to make things reliable, but the world isn't perfect, nor are any of us.
Yup. Now everybody else has learned from BBN's mistakes and from your anecdotes. Thus we make the network more reliable one step at a time. Michael Dillon - ISP & Internet Consulting Memra Software Inc. - Fax: +1-604-546-3049 http://www.memra.com - E-mail: michael@memra.com
