Not always no. This week we did a pretty large update to www.beautifulpure.com involving some lengthy database work. Whilst this is happening, of course transactions cannot happen on the site.
So, we do this work in the dead of night and plan the downtime. With appropriate planning, testing the deployment as well as testing the new functionality and faultless procedural execution of the deployment we still met our 99.9% uptime SLA.
Overall for this year we are running at 99.91% which roughly equates to 6.5 hours of downtime accross all clients for the whole year so far.
The next part of this analyis will take into account planned vs unplanned downtime and of the unplanned downtime - what time of day did it occur?
Watch this space.
