Scheduled - Dear Client,

This maintenance has been postponed until the 7th of April.

As part of our continuous improvements to our platform, we will be moving our REST API end points in Eastern US to a new set of load balancers.

This will only impact clients that have IP whitelisting in place for our IPs connecting to:
* api.clxcommunications.com
* api-sms.us.clxcommunications.com
* sms.api.sinch.com
* us.sms.api.sinch.com
* us1.sms.api.sinch.com
* geo.sms.api.sinch.com

The maintenance is scheduled below:

Type: Scheduled Maintenance
Maintenance: REST API

Start Time: 2021-04-07 08:00 UTC
End Time: 2021-04-07 09:00 UTC

Impact MT: No expected impact
Impact DR: No expected impact
Impact MO: No expected impact

FQDNs being moved:
* api.clxcommunications.com
* api-sms.us.clxcommunications.com
* sms.api.sinch.com
* us.sms.api.sinch.com
* us1.sms.api.sinch.com
* geo.sms.api.sinch.com

Additional IP Addresses to be added:
• Clients connecting to Sinch: 13.248.202.0, 76.223.66.78
• Clients accepting DR's or MO's from Sinch: No Change Needed.

Please add the additional IP Addresses to the whitelisting (or any IP rules) on your outbound message flows that may prevent your platform from sending messages to Sinch.

Please ignore the maintenance if your application/organisations uses FQDN's api.clxcommunications.com or the other listed FQDNs and do not use our IP's in your API configurations, IP whitelisting or firewall rules for your outbound traffic to our platform.

If you reach our API platform via an IPSec VPN tunnel, this change will not impact you.

We appreciate your patience and apologise for any inconvenience experienced during this maintenance period.

If for any reason the maintenance is extended or cancelled we will advise you accordingly.

Please contact support@sinch.com should you require further information or assistance.
