I have to say I am
very disappointed in the support I have received from OVH regarding this issue.
My server (mSP) came with an ASUS motherboard and a Realtek NIC. Upon receiving the server I noticed the server would crash at least once a day and I had many interventions over the 1st months rental.
I managed to stumble upon a thread on these forums regarding the issue, there are also various threads around the internet from people with the same issue.
Apparently the Realtek 8168 doesn't play well with certain Linux Kernels, the only "fix" that OVH could offer was to use an OVH 8168 patched Kernel, not really a fix if you plan on using custom Kernels or things like Proxmox.
I had a ticket back and forth with Felix that was closed after I agreed to use the OVH 8168 Kernel. Everything worked fine for a while until I noticed my connection would drop, sometimes it would kick me off SSH and other times SSH would just freeze for 5 seconds, this was evident in the syslog:

Sep 30 03:00:15 kernel: r8168: eth0: link down
Sep 30 03:00:19 kernel: r8168: eth0: link up
So, I open another ticket on the 30th September, this time I have to go over everything again and ask them to change the Mobo/NIC to another model because this network card obviously doesn't work well in Linux.
The technician carried out some tests and eventually arranged an intervention:

If you agree, please fix the date and time of the intervention.
I responded and told them to carry out the intervention as soon as possible as this was now the 4th day of waiting for this issue to be resolved.
So, the intervention was planned, I receive a ticket:
An operation was added for ********.ovh.net to the list of
interventions at 2013-10-03 15:50:00.
Here are the details of this operation: BIOS check
You will be notified when work will begin shortly before
the intervention.
BIOS check?! What happened to RAM and PSU swap?
The intervention on *******.ovh.net has been completed.
This operation was closed at 2013-10-03 19:35:47
Here are the details of this operation:
BIOS check
Great... a BIOS check. By this time it's already too late to phone OVH technical support and I'm left wondering what to do.
So for 2 months I've had intermittent connection to server, multiple crashes, 4 days after submitting a ticket all I've got out of it is a BIOS check. The RAM and PSU replacement (which I don't think will change anything) has been somehow forgotten about.
I've phoned technical support on numerous occasions only to be told that I have to submit a ticket and wait for a reply, they can't do anything for me. In that case, why does technical support even exist?
After I questioned the ethics of knowingly selling servers with faulty hardware and not following their own SLA, a gentlemen at technical support told me that I was lucky my ticket was even replied to because "
you usually have to pay to get a reply for these things" - which blew my mind, I'm pretty sure it says if the fault is not your own you don't have to pay.

We can replace power supply, a hard disk, RAM or the whole server is substituted.
The SLA agreement speaks volumes to me, OVH obviously can't or won't replace my server with a new one because it involves swapping the entire server, instead they promise to replace parts and fail to do so.
This is not good enough OVH.
