Maintenance work was carried out in April on deprecating older, insecure versions of the TLS protocol on our Delivery API (please see https://www.contentfulstatus.com/incidents/1svf18qn64qy
We have detected a portion of our Delivery infrastructure where this was not completed. To finalise this work, this will be done between 09:00 UTC and 11:00 UTC on Tuesday November 14th.
There should be no impact to the Delivery API service. Please refer to the original maintenance notification for more details.
