OVH Network Outage 18/07/2013

Tonight, OVH disappeared from the internet. From around 01:16 AM till 01:26 AM, none of OVH’s entire network could be reached. With a reported 150,000 servers in the EU and 360,000 servers in Northern America, OVH is one of the largest providers in the world. Not being able to access any of their leased services means that a lot of connectivity is lost…

So what could have happened? OVH Network Status page states that 3 Route Reflectors have reloaded (read: restarted) after an issue with their OSPF routing processes caused a crash. We can find out which systems these were by finding an OVH IP that is not responding and cross referencing it with a resource such as bgp.he.net. So, we have the Autonomous System Number  (ASN) of the devices under OVH’s control, we can now see how much of the internet they own… http://bgp.he.net/AS16276#_prefixes shows us the networks allocated to this system in slash notation format. To put this into perspective, there are 10 /16 subnets alone in the allocated prefixes list… That’s 655360 IP addresses which make up 40% (as a quick estimate) of the OVH Network…

Here’s what happened as shown in BGPlay:

I’m still looking into this as it’s just occurred and I need sleep :P Will post updates soon.

OVH BHS Canada Beta Servers

So about two weeks ago I signed up with OVH.net for one of their beta servers, OVH have built a huge new data centre on the border of the USA and Canada (probably because Canada is french speaking). This datacenter is HUGE, housing around 360K servers. Anyways, OVH assign around 90 beta servers every weekday for testing. You can get your own by following #OVH on twitter and checking their tweets at around 6AM GMT+1. Here are the stats of the dedi I received today, I hope to put it to good use (suggestions in the comments if you have any)!

  • 16 gb RAM
  • 1tb hdd
  • 100mbps connection
  • Quad Core Intel(R) Core(TM) i3-2130 CPU @ 3.40GHz
  • Running Debian Squeeze by default (6.0)
  • 1 IPv4 Address
  • /64 subnet of IPv6 addresses (standard with every OVH server)
  • Free to test till Mid August!

So where does OVH stand in relation to other online retailers/hosts?

Google: 1 million+ servers
Microsoft: 500k servers
OVH: 100,000 servers + 360,000 servers
HP: around 300k servers
SoftLayer: 100,000 servers
Akamai Technologies: 95,000 servers
Amazon: undisclosed, certainly > 70k servers
Rackspace: 78,717 servers
Intel: 75,000 servers
1&1 Internet: 70,000 servers
Facebook: 60,000 servers
LeaseWeb: 36,000 servers
Intergenia: (PlusServer/Server4You), 30,000 servers
