Support ending for TLS 1.1
Scheduled for Apr 21, 17:00 - 18:00 AWST
To ensure compliance with best practice and Landgate security protocols support for TLS 1.1 will be ending on 21/04/2021.

TLS is the acronym for Transport Layer Security; it’s a protocol that encrypts and authenticates secure connections across the web. TLS 1.0 and 1.1 were superseded by TLS 1.2 in 2008, which has now been superseded by TLS 1.3.
Most modern internet browsers no longer support TLS 1.0 and 1.1. See our 2018 blog post about TLS for more information on TLS modernisation

What does this mean for SLIP data services? From 22/04/2021 only TLS 1.2 will be supported. Applications using TLS 1.1 will not be able to connect to SLIP data services. If you are unsure about what protocol your applications are using please check with your IT support or software vendor.

As of April 16, 2019, Esri ArcGIS Online services only accepts connections using TLS 1.2. Some software, like ArcGIS Pro, are already TLS 1.2 enabled. Other Esri software, such as ArcGIS Desktop, uses TLS 1.0—this software requires a patch or configuration change to support TLS 1.2 connections.
