SliceHost was acquired by RackSpace in 2008. The SliceHost brand hasn't operated in many years, it was time to remove it from our listings.
I am happy to announce we've added Windows Azure hosting platform to Review Signal today. Azure is definitely a big player in the cloud server market. It was also one a very notable absence in our listings. Now that we've added Azure and Amazon AWS in the past few months, our cloud listings for IaaS providers looks a lot more complete.
Windows Azure comes in with a 70% overall rating which is quite respectable and puts it right next to RackSpace on the rankings. Although the support scores seem to be a lot lower at an underwhelming 56%.
