Omega8.cc

Omega8.cc builds BOA (Barracuda, Octopus, Ægir), the open-source hosting stack behind the Ægir control panel, and hosts on it: Drupal and Drupal CMS, Pressflow 6 and Drupal 7, Backdrop CMS, Textpattern and Grav. Hosted plans run on the hardened Ægir stack, BOA PRO licences support Ægir hosting on your own servers, and BOA LTS stays free and open source. We hold the technical stewardship of Ægir 3 and carry sites past their platforms' end-of-life dates. In web hosting since 1995.
