To be honest, the poor support was one of the reasons we moved away from Linode. We were in the Newark datacenter for about 8 months with 12 linode boxes. Had frequent issues with their load balancer and most of the time when we told them there was a problem, they asked us to prove it.
A few times we had extended outages due to "unscheduled maintenance"
Prior to running my business on Linode I had a single VPS with them for 2 years for personal stuff. I had zero problems... so YMMV. Overall, I'd still use them again, but not for mission critical stuff after that experience.
