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. We securely synchronise call recordings nightly to another datacentre.

Datacentre Commitment

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

Weekly Image Backups

We take weekly image backups, 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.

Quick Failover Time

We can fail over your 3CX phone system in as little as 15 minutes. Once failover has been manually initiated, the failover instance can take as little as 5 minutes to become live. After this, normal service will resume within approximately 10 minutes, defined by the TTL of the 3CX FQDN DNS record required for reprovisioning.

Failover is only initiated when an outage has been identified and has lasted longer than 30 minutes, as DNS failover itself causes downtime.

Failover Requirements

Yellowgrid's server IP addresses are required to be whitelisted in order to monitor availability, perform backups and to invoke DR as required.

We can only failover instances that are running supported versions of 3CX. The failed over instance will be running the latest 3CX version. The following versions are not supported:

  • Alpha
  • Beta
  • Release Candidate
  • End-of-life

Yellowgrid's hosting services are provided by OVH (primary) and Digital Ocean (failover) each providing a minimum SLA of 99.99%.
