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.

Nightly Image Backups

We take nightly 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.

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 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%.
Customers can refer to the Data Processing Addendum (DPA) found in their Customer Portal.
All hosting is located in your chosen territory.

Support

We will provide "hands-off" support for all supported 3CX features and provisioning methods.

Our internal Service Level Agreement require us to respond to calls within four hours, although response is usually much quicker than this. The standard agreement provides cover during normal business hours of 9:00 until 17:30, Monday to Friday.

Remote Support includes support for the normal operation of 3CX phone system, service pack upgrades and upgrading phone system to new versions and troubleshooting where necessary. Ultimate support responsibility remains with 3CX.
