Dear Client,

We are disabling TLS1.0 and TLS1.1 cipher suites from the TLS-enabled API access gateways in EU3 below.

Type: Scheduled Maintenance
Affected site: EU3
SMPP FQDN: smpp-eu3.clxcommunications.com / eu3.smpp.api.sinch.com (93.158.78.4) port 3601
HTTP FQDN: http-eu3.clxcommunications.com / eu3.httpsms.api.sinch.com (93.158.78.4) port 3801
ENUM FQDN: enum-eu3.clxcommunications.com / eu3.httplookup.api.sinch.com (93.158.78.4) port 3701

Start Time: 2021-09-07 03:00 UTC
End Time: 2020-09-07 04:00 UTC

Impact: For clients connecting to the TLS-enabled API access gateway and port combinations above using the below TLS ciphers.
TLSv1, ECDHE-RSA-AES256-SHA
TLSv1, DHE-RSA-AES256-SHA
TLSv1, AES256-SHA
TLSv1, ECDHE-RSA-AES128-SHA
TLSv1, DHE-RSA-AES128-SHA
TLSv1, AES128-SHA
TLSv1.1, ECDHE-RSA-AES256-SHA
TLSv1.1, DHE-RSA-AES256-SHA
TLSv1.1, AES256-SHA
TLSv1.1, ECDHE-RSA-AES128-SHA
TLSv1.1, DHE-RSA-AES128-SHA
TLSv1.1, AES128-SHA

There will be no impact and no action is required if your TLS client currently support any of the stronger cipher suites below when connecting to the TLS-enabled API access gateway and port combinations above.
TLSv1.2, ECDHE-RSA-AES256-GCM-SHA384
