Wow, how long did you allege to have been in network/sys admin?  20 
years? Really? I think you made a typo and and it should have read 20 
minutes, ya know I have refrained from posting no here for a long time 
(apart from fact I rarely read the list), and I was not going to feed 
the trolls, but sometimes the smart mouthed know nothing, need to bitch 
slap upside the head so thats why I am devoting about 60 seconds to you.

Of course there is, networks dont throw away many hundreds of servers 
valued $7K to $10K, nor $100K+ storage systems, or $40K routers, LB's or 
switches, just because they got drenched - with power isolated.

You will never be a customer _or_employee_ of mine, trust me on that 
one!

Got nothing to with insurance, it might take 2 days to dry out and get 
back up and running, it will take an awful lot longer to get offsite 
backups and restore every last one of them.

I hope your employer reads this list, because he/she should be seeing 
alarm bells from your comments.

yep, you sure did fail basic engineering

Wow, you really are clutching the fantasy straws arnt you, perhaps your 
country lacks modernisation, I can go to the side of my house and 
isolate the panels with a flick of a switch, strangely enough and I 
guess in your eyes horrifyingly called "solar isolator" that stops the 
panels providing power to my electrical circuits, yes, there might be 
power from panels to it, but thats not going to affect my power circuits 
or equipment
