I did have a server with Burst. I left quite a few months ago.
Setup time was great back then. Less than 24 hours, the price was good too. I was using this dedicated for development, not hosting anything important.
A fair few months ago, they had network problems, for the second time in 7 months. For around 2 weeks, my server, and many others, had terrible connections, it was packet loss. It made the server unbearable to operate.
Now, I would have stuck with them, but this was not the first time it had happened, about a day after my server has been setup, the same problem occurred for around 3 hours, and once again, it was not just me, it was most people’s server with them.
Not only that... But the random network restarts to drops. Sometimes down for over 20 seconds (The server stayed online for all that time, but the network (Entire client network) was down. This happened around every 2 hours, and lasted for around 2-20 seconds.
Not a biggy you might be saying, but considering I was in SSH running commands... Yes, it was a biggy for me.
Their TOS is insane... Read it VERY carefully, as they can manipulate it to whatever they want it to mean. If you do something they don't like (Like burst to max out the line, they won’t hesitate to enforce their sham TOS on you.
Overall. For a development server... They are not bad... Cheap. But for anything else (Reliable webhosting, game servers). I would not even consider it.
Considering the network (so some say) is even worse now... And the reason some people don’t notice it, is they are not in SSH, and it sometimes only lasts for 2-3 seconds...
