A small number of our customers are experiencing issues when PHP needs to resolve DNS entries when accessing external HTTP(S) ressources, eg. via curl, drupal_http_request or file_get_contents.
Currently we only see these errors in the applications error.log with PHP 7.0.
The issues results in error messages like:
* php_network_getaddresses: getaddrinfo failed: No address associated with hostname
* php_network_getaddresses: getaddrinfo failed: Name or service not known
* cURL error 6: Could not resolve host
We are seeing these errors very sporadically and are rolling out a fix at the moment.
