Sorry – the system is down
What are the arrangements if your provider's IT is “down”?
How thoroughly have you explored their backup arrangements?
For example, a quick internet search for Amazon Web Service (AWS) outages soon reveals the extent to which businesses can be adversely affected in the event of a datacentre power failure or human error. Even an initial problem that may have been short-lived at source, can have a significant ripple effect across the wider network of users.
If your business is affected, you need to understand the implications that has for your business. Your clients may lose visibility of you, perhaps access to your sales pipeline will be interrupted, and then, of course, there is the reputational damage that you will suffer.
Of course, not all downtime is unplanned. It is inevitable that system upgrades and maintenance will need to be carried out from time to time. It's important that you understand how that will impact on your business and what the contingency arrangements are. Don't wait until it happens to discover there is no backup plan!
