Hi Matthias
This depends on your customer base. Fact is, that you'll never have a
window where no customer is affected. However you'll have that certain
spot in your RRDs, where the usage is the lowest. This would probably
your preferred maintenance window.
In my recent jobs, the sweet spot was usually the night from Sunday to
Monday at around 2:00-3:00 CET. This also has the advantage, that if
something goes wrong, you'll be in the office after the maintenance
anyway and can fix things.
As for the interval - it again depends on your needs. Furthermore it
depends on the redundancy of your platform - the more redundancy, the
less outages are caused by maintenance. The best thing is if you can
announce a maintenance which generates no service interruption.
Customers love that, because it shows that you keep your systems
up-to-date (marketing!) and they don't have any impact on their services.
Cheers,
Viktor

Good monrning
I'm trying to figure out the best day, time and interval for our
maintenance window. When do you have your maintenance windows? What
interval? How does swisscom, cablecom and the others do it?
Thanks and best wishes,
Matthias
