Scheduled - Dear Valued Customer,

The following is a message from Intermedia, regarding their scheduled maintenance:

As part of our continuous commitment to provide the most highly reliable and secure cloud network available, we will be performing a network upgrade to our infrastructure. This upgrade is to move the backend infrastructure into Network Availability Zones, which provides redundancy and resiliency, resulting in improved availability of your services.

We will cut over to the new Availability Zones at 1 a.m. Eastern Standard Time on November 14th. The cutover will take seconds.

We will be adding IP new endpoints to our system which MAY require you to make some changes if you use the features described below.

New IP endpoints to whitelist and information you will need:

APIs: For customers using API, the IPs listed below will need to be added to your network (firewalls, routers) IE: “Whitelisted”. This can be done ahead of the migration.
64.78.55.19 and 64.78.55.20

FTP: For customers using FTP, the IPs listed below will need to be added to your network (firewalls, routers) IE: “Whitelisted”. This can be done ahead of the migration.
64.78.55.19 and 64.78.55.20

Customer Owned External Storage: For customers using their own (Azure / AWS / other) external cloud storage to store their call recordings, access must be allowed in the storage cloud (ACL/Firewall) to our public IP addresses:
64.78.55.19 and 64.78.55.20


Start time: Nov 14, 01:00 EST

Estimated duration: 1 hour


WHAT DO I NEED TO DO?
Whitelist the new IP endpoints and obtain the necessary information, as explained in Intermedia’s maintenance notification section ‘New IP endpoints to whitelist and information you will need’
