Also Linode is a security nightmare and Hetzner doesn't always have instances available.
To be fair, Rackspace could also be a security nightmare just waiting to be discovered. For example, as of about a year ago, the way Rackspace generated the initial root passwords for cloud instances was by taking the hostname and appending a bunch of random characters to it. Unfortunately, they put a DES hash in /etc/shadow, so only the first 8 characters mattered, most or all of which were taken up by the predictable hostname. And yes, root logins over ssh were on by default. When this was reported to them, they initially denied it, and only acknowledged and fixed it after much wrangling and, in my opinion, an excessive amount of time.
That's clearly the v1 (Sandy Bridge) E5 2670 that came out in March 2012, with 8 cores per CPU, 16 cores per machine, and 32 logical threads.
The v2 (Ivy Bridge) E5 2670v2 came out back in September with 10x 2.5GHz cores per CPU, or 20 cores per machine, and 40 logical threads. As well as having slightly improved performance/clock due to the new architecture.
Not that it should really matter; once you get up to the prices of the Performance 1 4GB or 8GB, bare metal makes more sense. An E3 1240v3 has 74% the performance of an E5 2670v1, and would obviously run circles around a 12.5% or 25% share of the E5, without even taking the I/O hit of running virtualization into account.
$2000/mo for a 60G box...
For that money you can buy an equivalent server every month.
And don't get me started on $4000/mo for 120G, that's almost two equivalent servers. Every month.
I understand why their costs might be higher (excellent support staff, always had stellar support from RS), but it doesn't really justify that much of a difference.
The advantage of a "old" hosting company is that it's less likely to go out of business in a heartbeat, it's not necessarily enough to convince me in paying more for the same services that I can get elsewhere.
