Hi, Vladis --
Thanks for the email. Unlike a number of ISPs operating in the same
geographic region as ourselves, a loss of core systems or connectivity
causes something more than the sweat on the forehead of the people
responsible for SLA-credit-avoidance... it causes a 100% revenue loss
for the period of the outage.
When you reach a certain size, in the UK at least, your business
insurance partners will expect you to demonstrate how you have taken
steps to avoid this entire outage.
When the company reaches another size, you may find your continued
employment also depends on some degree of constant availability.
This is what I mean by 'will never do'. A lot of small firms can sit
out an evening without trading. To us, this represents 'real pain'.
Best wishes,
Andy
