There was an outage at London stock Exchange that went for more than 7 Hrs. And believe me that’s serious because it’s a STOCK EXCHANGE. Couple of months ago you would have noticed the Microsoft “Get the facts” campaign. There, in one of those they claimed “London Stock Exchange chooses windows over Linux for reliability”.
I don’t claim Linux is superb for reliability, but it lets it’s server do the talking rather than it’s marketing.
Windows is “Lipstick on the PIG”.
