Our' Web, Email and DNS hosting services are built on top of well-known open source software.
Our infrastructure runs on a combination of different Linux flavors where each service is periodically
optimized to deliver the best possible performance.

Some of the technologies that we are currently using include:

NGINX is a web server known for its astonishing performance and small footprint.
This is exactly why we chose it to be our core technology: it sits extremely well in shared environments.
Why? Because RAM is the single biggest hardware issue affecting web server
performance (ref) and NGINX
uses significantly less RAM than others.

Its development began in 2002 and today is used by some high-traffic sites such as:

WordPress, Hulu, Github, Ohloh, SourceForge and TorrentReactor. More info.

PHP-FPM is an alternative PHP FastCGI implementation with extra features that
translate into a performance boost for sites running on it. Its development started
back in 2004 and since May 2010 it has been added into PHP's core.

MySQL is the most popular open source database system and can be considered as
the Internet de facto. It is currently being used in a number of high-profile websites
such as Facebook, YouTube, Flickr, Google, Wikipedia, and others.

PowerDNS is one of the most popular open source DNS servers used by Wikimedia to
handle all their DNS traffic.

It offers a very high domain resolution performance and supports a large number of different backends.

qmail is mail server software (i.e. Mail Transfer Agent) than runs on Unix. It’s the second most
popular main server on the Internet. It was written by Daniel J. Bernstein as a more
secure alternative to Sendmail. When it was released qmail was significantly faster than
Sendmail, especially for resource intensive tasks such as mailing list management.

Postfix is also mail server software which was developed
as a faster, easier-to-administer and more secure alternative to
Sendmail. We use it in combination with qmail (and others) to provide reliable
email hosting services.
