Hey Guys,
There are some big differences between Kimsufi (OVH) and GlowHost.
First of all, the Kimsufi range are budget servers. Yes, they are powerful high specification servers, but the overall performance is is a lot lower than what GlowHost offers. This is because the hardware is used, re-used, used again and again. The hardware is far more likely to fail with OVH. GlowHost has it's servers built from scratch with new drives and hardware for each customer - this is one major difference.
While the price is attractive at OVH, you have of think of the implications. Many users are reporting slow network performance, downtime and other issues. You only have to spend a few minutes looking around Web Hosting Talk to find the reviews that shed light on this kind of issues. Here at GlowHost, we are housed in premium datacenters with premium carriers. We do not use budget bandwidth providers and our routes into different parts of the world are some of the fastest.
The other thing to note about OVH is the bandwidth limit. They advertise unlimited, however they only allow 5Tb of bandwidth at full port speed outside their own network before they limit the port speed to 10mbps. By today's standards, 5Tb is not a lot of bandwidth. On our own new range of servers, we offer 100Tb of bandwidth (yes, one hundred) at full 1Gbps.
Another major difference is the locations. The OVH flagship datacenter is in France. I believe they operate in Canada and Netherlands also. While the EU locations would be acceptable for traffic for the UK, Germany and surrounding regions, it would be very slow for pretty much the rest of the world. That just goes back to the statement about premium bandwidth providers. Europe does not have the same level of bandwidth that the US has to offer. One serious issue with Canada is their law regarding spam. Canada currently does not have any kind of law against spammers. While it is frownd upon, Canada attracts a large amount of fraudulent activities due to it's inferior laws. This would be something to consider. Would you really want to be on a block of IP's that has been blacklisted by all the major blacklists? It goes hand in hand with the price. Spammers will often look for low cost solutions to operate their schemes and scams.
One last thing to note is the level of support. I notice you mentioned that you had made a user error, the support did correct it and help you fix it - however, with the amount of servers they have right now, to support everyone fully they would need over 7000 system administrators. This is something that I doubt they have. It is highly unlikely they monitor the servers hardware. It would be interesting to know, if your server went down, a hard disk failed or it needed some love and care, how would they deal with it? My brief research around the various web hosting forums shows some shocking issues with OVH, ranging from several days to replace hardware to an accidental format of a hard disk due to them getting the server muddled up with another client.
At GlowHost, we have our own in house monitoring software that monitors various different things on your server. We are instantly alerted to the problem and often fix it before the customer is even aware of anything. The other thing to mention is we have a low server-to-administrator ratio, compared with the competition meaning we can react quicker to critical situations and work closely on a solution.
I hope you find this information useful and do let us know if you have any questions about anything.
