Backup & Monitoring

Instance Monitoring

We monitor our instances every minute to ensure that infrastructure is available. We perform daily snapshots of the instance and retain 5 versions.

Nightly Config Backups

We perform nightly config backups, which are encrypted and stored securely at another datacentre. We securely synchronise call recordings nightly to another datacentre.

Nightly Image Backups

We take nightly image backups which are stored at our secondary datacentre allowing for rapid recovery. No manual backup plan is required for our subscribers as our hosting is both resilient in use and protected in the event of a disaster.

Datacentre Commitment

Both primary and failover datacentres provides a monthly availability commitment of 99.99%.

Quick Failover Time

We can fail over your 3CX phone system in as little as 15 minutes. Once failover has been manually initiated, the switch to our secondary datacentre can take as little as 5 minutes. After this, normal service will resume within approximately 10 minutes, defined by the TTL of the 3CX FQDN DNS record required for reprovisioning. This is reduced to 5 minutes for 3CX Enterprise licences. Failover is only initiated when an outage has been identified and has lasted longer than 30 minutes, as DNS failover itself causes downtime.

Yellowgrid's hosting services are provided by OVH (primary) and Digital Ocean (failover) each providing a minimum SLA of 99.99%.
Customers can refer to the Data Processing Addendum (DPA) found in their Customer Portal.
(*) Yellowgrid's server IP addresses are required to be whitelisted in order to monitor availability, perform backups and to invoke DR as required.
All hosting is located in the UK.
