A++ post, would agree again.<div><br></div><div>It's supremely easy to sit back and criticise people for not doing blank to prevent an outage or datacentre failure. You don't have to peruse Whirlpool for long after any outage to hear people 'why didnt they do this or that'. And in a perfect world, our HA plans would all go exactly to plan and every scenario could be prepared for and anything in the world could happen and everything would be fine anyway.</div>
<div><br></div><div>The reality of it is, if you've spent any real amount of time building & managing datacentres or maintaining highly-available services, you know that a HA plan is really only as good as the circumstances you can feasibly spend money preparing for. Sometimes it means running to Mitre 10 to buy their entire stock of fans. Other times it means carrying hundreds of litres of diesel up a dark staircase.</div>
<div><br></div><div>There is basically no amount of money you can spend that guarantees your stuff won't fall over, so my hat is off to the people who got hit by a bad situation and put some hard work into staying online.</div>
