The price difference between a Dedicated Server & a VPS is quite a bit, let alone the cost of SSD drives currently:facepalm:

KnownSRV wasn't sold in the end. We invested piles of benjamins and we survived the hard times.
If you were migrated last I believe I know who you are. Your site was causing VPS load to go over 50 at peak times, on highly optimized setup(nginx, fcgi, caching etc). There is something on the site that uses way too much resources for a VPS - you can start from your site, it's where the problem lies most likely.
Good luck!
