your biggest **** up..

There's some classics in this thread!

Back when I was a trainee system admin we had a company come in to install a rack and fill it with new servers. They left the manuals kicking around and so I thought I'd read up on how it's done. It's then I realised they had installed the rack back to front before filling it. We'd paid extra for the installation.

Also, the first time I went on site at a new customer I was looking at upgrading their servers. I was messing around near the back of them and hit the UPS off switch by mistake. Everything was fine except the firmware was corrupt on one of the managed switches. Power cycling it is the only time you'd notice. They're still with us.

Worked for a Cafe about 3 years ago as a chef, had to move all the stock in the freezer around but it was really cold so turned it off to do it so the fan wasnt freezing me....did i turn it back on?

only about 2k worth of stuff destroyed, they blamed the freezer and claimed on insurence. PHEW!

About 9-10 years ago, I had just started working in IT for a sizeable national company.

My biggest **** up was plugging a known virus infected laptop into the company network when I said 'don't do that' to the sales rep to prevent the chaos that did unfold.

In my defence, the story was that I was going out on a remote site visit anyway and the boss at that job was the sort where if you had done 99 jobs in a day he'd want to know why the 100th hadn't been done fearing that this clean up job might of taken me much longer that what I anticipated ( Hofstader's Law ) and thinking that if I go to my boss and say 'i've cleaned up this laptop but i've not done all those jobs needed in the site visit' decided the site visit was more important.

I copied various clean up tools to a cd to run on the laptop, but the cd hadn't burnt correctly, so in my haste hooked the laptop up to the network and...

Found out that the other guy didn't take things like making sure AV had been updating properly ( it was him who was still showing me 'the ropes'!). The entire network collapsed under the traffic now flowing from every computer on the network.

I learnt my lesson that haste makes waste, and that unless you take control of important things yourself you can't rely on them 100% - I decided to teach myself the systems after that. Every cloud has a silver lining

I called my teacher 'Mum'

How many years did it take before the ribbing stopped?

Anyway.
My biggest ****-up was when I was the evening Quality Manager on a cooker factory and I made the decision to let the whole production run with the wrong coloured facia & side panel trims on because they looked OK and we hadn't got anymore.
The following day I was told all production would have to be reworked for a cost of £75,000

About 3 months later we had run out of the correct trims again and the boss decided to run with another colour because nobody would notice.
I just stood there with a big WHAT on my face.
