Temporary failure in name resolution

[Nasjoe]

Hi !
On my two servers ( with different ip and locations ), i got this 'til this morning :

HTTPSConnectionPool(host='us16.api.mailchimp.com', port=443): Max retries exceeded with url: /3.0/lists/9553bacb88/members (Caused by NewConnectionError('<urllib3.connection.HTTPSConnection object at 0xb1f5c6f0>: Failed to establish a new connection: [Errno -3] Temporary failure in name resolution'))

Dns changed ?

Many thanks for your work !
