I have been using their service over a month and can express the point that Glowhost is a solid hosting provider with services that can scale. I haven't tried their new cloud stuff, but I am excited to try it when I have a little extra money, it sounds really cool.
Their ticket support has always been very helpful. They are always available for my questions and they are quick to respond. I would rate them as a very reliable service and the price is right.
Overall, Glowhost is a great host that I would recommend. My site is always up and running.
What domain do you host with them? Just wonder, how did you find and why did you choose them? How fast was their support (how much time does it take to answer a ticket?).
Although oversellers ("unlimited disk space; unlimited bandwith") - it's OK, if you are feeling good with them.
