OVH host crashes during scheduled maintenance

OVH host crashes during scheduled maintenance

OVH, Europe’s largest hosting provider and the world’s third largest, broke earlier today in what looks like routing configuration issues during scheduled maintenance.

OVH has 32 data centers with more than 300,000 servers on four continents and a total global network capacity of 20 Tbit / s.

It provides web hosting, cloud computing services and dedicated servers to 1,300,000 corporate clients around the world.

Failure caused by improper router configuration

“We will be performing maintenance on our routers on VIN DC to improve our routing,” the company said on its status page before its servers went down.

“Maintenance is scheduled for Oct 13/21 from 9:00 am to 10:30 am (UTC + 2). No impact expected, aircraft will be isolated prior to change.”

However, due to unknown issues encountered during scheduled maintenance, hosting provider’s servers became inaccessible, dragging customer sites with them as well.

“Due to a human error during the reconfiguration of the network on our DC to VH (US-EST), we have a problem on the whole backbone. We are going to isolate the DC VH and then repair the conf,” said Octave Klaba , founder of OVH. Explain.

“In recent days, the intensity of DDoS attacks has increased dramatically. We have decided to increase our DDoS processing capacity by adding new infrastructures in our DC VH (US-EST). A bad router configuration caused the network to go down. “

According to reports [12], the current failure only affects the IPv4 infrastructure, the IPv6 infrastructure still being operational and accessible via the Internet.

When they try to connect to the OVH site, users are currently seeing “Error 503: Backend unavailable” errors explaining that “This type of error generally results from an unavailability of servers behind the IP Load Balancing”.

Visitors are encouraged to refresh the site or come back in a few minutes and contact the OVH support team if the problem persists.

The host’s status page also crashed with company servers during the maintenance process, with the page now displaying “Connection timed out. An error occurred while connecting to status .ovh.com “, errors.

Earlier this year, major sites were also taken offline after the OVH data centers in Strasbourg, France burned down in March.

Its SBG1, SBG2, SBG3 and SBG4 Strasbourg data centers were closed to contain the damage caused by the fire that started in SBG2.

The list of affected customers included the video game maker Rust, free chess server provider Lichess.org, telecommunications company AFR-IX, encryption utility VeraCrypt, briefing eeNews Europe, cryptocurrency exchange Deribit‘s blogging and document sites, the complex of art buildings Centre Pompidou, and many others.

The founder of the company later explained that SBG2 was an older generation center built in 2011 and that OVH was working to replace the old infra with newer technology.

Update Oct 13, 04:59 EST: The OVH network is slowly recovering after its outage at 07:20 UTC this morning with an American router with a faulty configuration.

“As of 08:22 UTC, all services are gradually returning following the isolation of network equipment in the United States,” the company said.

Klaba tweeted earlier than the router with the wrong D2 configuration was cut off from the network.
