At this point WPMU Dev does not have the best Wordpress hosting. In truth it's okay but not even nearing great let alone the best. A few things you should know: 1. Hard limits on disk space with no flexibility and no ability to add storage without upgrading and considering they use Digital Ocean and we all know how flexible and inexpensive DO storage is this is unacceptable. This is my number one reason why they are nowhere near a small business class host. 2. The support you'll receive is hit or miss. Of the most recent tickets I've had two were handled fairly well while the last two were abysmal failures and I had to seek help at my other host who handled it very quickly. 3. Do not switch all your hosting to WPMU Dev. Don't put all your eggs in their basket just yet. Maybe in a year or so when they get a few issues handled and hire far more knowledgeable support techs but right now avoid giving their hosting 100% of your sites. 4. Their plugins are generally pretty good but they're starting to open up premium versions of plugins to be freeware via wordpress.org and each time they do this they're essentially removing value from the $50 I pay a month (and I'm certainly not paying that for their hosting). 5. The Hub - it's okay. It's not great but it's easy to use and that's helpful. It's fairly limited in comparison to most other hosts. 6. I like the CEO and I think he's a cool guy with good intentions but I have noticed he has a tendency to promise things that they aren't offering or seem to be close to offering. He stated that their hosting service has free SSL certs - no they don't. Allegedly they will at some point in the future but not now. 7. You'll receive three $10 bronze plans and although their site also states that you'll receive $30 in hosting credits DO NOT try to use those hosting credits for the $25 hosting plan. And when you need more than 10 GB of disk space you'll have to upgrade and pay $15 extra a month just to receive an additional 5 GB so the math doesn't work on that at all.
