All Apex Callouts Across Production Experiencing Error: System.CalloutException: Read timed out

Did anything change in Salesforce over the weekend? Across all of our Apex Call Outs we are now getting this error:

System.CalloutException: Read timed out

Could this be associated with the new TLS requirements? Anyone else experiencing something like this?

Is your environment compatible with TLS 1.1 or higher??
The only thing Salesfroce changed recently was to deactivate TLS 1.0 across all instances.
They were sending notices for the last two years about it as it was happening in stages all over globe.

Make sure thats not the case.

Other than that I cannot say what might be the cause.
Hope this helps.
