Earlier today OVH, the biggest hosting provider in Europe suffered an hour outage during the scheduled maintenance. The reason for the outage is said to be because of the routing configuration issues.

OVH is certified ISO 27001:2005 for offering and operating dedicated cloud computing infrastructures. OVH has 32 data centers and more than 300k servers spread across the four continents and a network capacity totaling about 20 Tbit/s.

OVH is the third-largest hosting provider in the world with over 1.3 million enterprise clients all over the globe. OVH is well known for offering cloud computing services, web hosting, and dedicated services.

Outage Caused Due to Bad Router Configuration

Before initiating the scheduled maintenance, OVH in its Twitter handle @OVHStatusFeed tweeted that as part of scheduled maintenance, they will be performing maintenance on their routers on VIN DC to enhance its routing.

But, sadly due to some unknown issues, the planned maintenance didn’t go well and made the server reachable. Several sites hosted on that server went down.

Octave Klaba who is the founder of OVH explained that after the accidental bad reconfiguration of the network on our DC to VH (US-EST), there is a problem with the whole backbone network. The DC VH needs to be isolated first then we will fix the conf.

Taking into account the rising intensity of the DDoS attacks, OVH has decided to expand our DDoS processing capacity by adding new infrastructures in our DC VH (US-EST). However, due to bad router configuration, the network went down.

The OVH outage only affected the IPv4 infrastructure whereas the IPv6 infrastructure was up and working fine.

Users faced Error 503: Backend unavailable while attempting to connect to the OVH website. Usually, this type of error occurs when the servers behind IP Load balancing are unavailable. The server is temporarily unavailable to manage the requests.

Meanwhile, OVH’s status page too wasn’t acessible during the scheduled maintenance. The status page showed error “The connection has timed out. An error occurred during a connection to”.

Earlier this year in March, several major websites went offline as fire destroyed OVH’s Strasbourg data centers.
