Between 3 and 5am on 21/07/2019, Gradwell engineers will be performing disaster recovery testing on our infrastructure. This test will see traffic from our physical platform routing over our newly rebuilt cloud-native platform. This will demonstrate that no matter what happens to our data centers we can ensure that your service keeps running smoothly.

Removing our reliance on physical data centers enables us to provide a much higher level of resiliency and therefore service up-time, even when faced with circumstances beyond our control. This test demonstrates our commitment to high-quality services and best-in-show platform architecture.

This testing is not expected to impact services however all VoIP services, including hosted VoIP services, SIP trunking, and IAX trunking, should be considered at risk for the duration of the maintenance window.

If you are currently doing any kind of IP filtering on your network, you will need to ensure this is fully up to date ahead of this testing. If you do not do so your services may not be able to connect to our cloud-native platform and will therefore not work for the duration of testing, nor in any disaster situations in future.
An up to date list of IP addresses you should ensure your firewall allows can be found here:

We would recommend avoiding IP firewalling where you can, as our network, and our suppliers' networks, can change at any time.

Please accept our apologies for any inconvenience this essential testing may cause.
