But more importantly they bring into question what protection you have in place across your business model.
When Sydney went down our Firm was pretty well placed because of 2 basic operational initiatives we have in place.
Firstly, we made the decision to host our Microsoft Exchange offshore with a global player. Therefore when the power was cut our Blackberry's still worked.
Secondly we have a setup around our Server where the power is cut it immediately switches to an external power source and does an immediate backup.
The offshore hosting of email is provided by many players and is actually very reasonably priced. The addition of the Uninterruptible Power Supply (UPS) is also pretty cost effective and when combined with a 1TB external backup means that your data will be protected.
This type of planning is very important - and if you are going through a corporate transaction it will also be a core area where the investor / counter party will definitely focus. Unfortunately when in a young company there are so many things on the plate, it is often overlooked.
So free up a bit of time. Have a look at how your IT system works. Work through what you will do in crisis. Put it into place.
