Announcement: Deprecating TLS 1.0 & 1.1 at shared servers
Dear Valued Clients,
What is TLS?
TLS (Transport Layer Security) is the protocol which secures HTTPS.
What is the version of TLS that depreciating?
There are currently three versions of the TLS protocol in use today: TLS 1.0, 1.1, and 1.2.
TLS 1.2 was published ten years ago to address weaknesses in TLS 1.0 and 1.1
Major providers in this industry including our software vendors only supports TLS 1.2 or newer now. Their system also enables TLS 1.2 by default.
We decide to deprecate TLS 1.0 & 1.1 in our shared environment.
When will we turn it off?
1st July 2021
What is the impact of this deprecation?
This deprecation will primarily affect non-browser software, APIs, and other internet infrastructure.
