Past Incidents

The following domains seem to have been reported as unsafe to Microsoft Defender SmartScreen:

• cellar-c2.services.clever-cloud.com
• cellar-fr-north-hds-c1.services.clever-cloud.com
• cellar-fr-north-c1.services.clever-cloud.com

This means that Microsoft Edge users might have issues downloading files stored on our Cellar services.

We are currently in discussion with them to get the domains unblocked. In the meantime, do not hesitate to click the "This domain is safe" link in the Defender screen.

EDIT 2024-05-07

We have setup a workaround. To avoid this workaround to be used by malicious users, we won't disclose it here.

Please come to us if you need to use it.

EDIT 2024-06-28

The domains were un-flagged a few days ago. The incident is now over.

(Times are in UTC)

At 2024-05-04 23:31 a database load balancer lost its network routes. The alert about that was set as low priority and did not wake up the on-call agent. At 01:23, another service failed because of that load-balancer issue. This time, the failure triggered a high priority alert.

The on-call agent investigated the issue and saw that the load-balancer was responsible for the other service's failure. They fixed the network issue. Every impacted service got back online around 01:45.

Clever Cloud's PAR region has 8 of those load balancers. Only the services that were trying to connect to this one got downtime. Some customers applications redeployed themselves and connected to another one, quickly fixing the issue.

On 2024-05-06, we made the first alert a high priority one. It should already have been high priority. We also made sure that every other "load balancer is unreachable" alerts were high priority ones.
