Midphase and all their affiliates BLOCK port 80 and Drupal cannot use update status module and therefore you cannot normally update/check against vulnerabilities.
After couple of months (now you cannot cancel the payed hosting) I was in a situation that if I wanted use update status module i became a message:
Unable to fetch any information about available new releases and updates.
Searching Drupal forum I found topics about HTTP request fails (about HTTP request fails module, solving problem with Midphase in January 09 ...), but at this time all solutions failed.
Communication with Midpase support - only answers - :

Hello,
I apologize but your server is now blocking outbound port 80 which is the port HTTP requests are made on. This is because of security vulnerabilities involved with this. Please let us know if there is anything else we can do to assist you. Thank you.
