As you might noticed this week the site was down. This was due to hosting upgrade to favorite IIS7 and some issues with dasBlog and one of it’s controls. Luckily I was able to fix it and also upgraded to dasBlog v2.2.

Hopefully there won’t be any downtime next… 10 years (next upgrade should be handled nicely :) ) Not like I am planning uptime 5 nines – 99.99999% :)

Now seriously:

If you planning your servers’ availability you might want to check how Microsoft.com Ops are doing it by taking a consultation from them for free. Why?! Because these are the results (as of 2005) – just imagine what are now:
