UPDATED 24.02.2013. All posts are recovered. Big thanks to Fabian for help!
As you may have noticed, my sites and blog was off-line few last days. The cause of this problem was a disaster in datacenter of hosting company who hosted my sites. For this moment sites are online but some data was lost. So Part 2 and Part 3 of SLA series also was lost. I will try restore them in next few weeks.
My apologies for that and big “thanks” to JaguarPC company.
PS What’s why the Windows Cluster is better. Looking into migration of my sites to Azure…
