Overall, this service started out great. The migration was easy and the cost is excellent. Since moving to WPMU Dev hosting about 4 weeks ago, my site has been down at least once a week. There's always some issue going on with the site. The most recent reason that my site was down was because of the Hummingbird plugin. Their support is available 24/7 which is awesome. But the level of support is vastly different. Sometimes they provide good support. Other times they just push the problem to me and force me to figure it out, like with a plugin compatibility test. Thiinking of switching hosts if this keeps happening
