Our infrastructure

In order to demonstrate what our infrastructure represents in terms of volume, taking all aspects together, here are the figures for the end of December 2010:

Our network consists of 11 routers and 57 Cisco switches. Traffic has settled at more then 8Gb at the end of the afternoon (a peak was registered during 2010 at over 12Gbit). Wheater map

The hosting hub consists of 680 Dell PowerEdge servers, which mean a total storage space of 400 TB (on which 229 TB are used).

Where email service is concerned, there are currently 160 servers, which ensure storage and delivery of email (POP/IMAP) and 40 SMTP servers dedicated solely to this task. We observe between 155 and 250 POP connections per second against 105 to 160 in IMAP for collecting email. The IMAP servers have see up to 41,000 concurrent sessions (so 41,000 email programs opened - or kept open - at the same time!).

The SMTP platform receives slightly more than 60 messages from the outside per second (the others are rejected for various reasons: blacklists, greylists, virus etc.) which represents more than 5 million new messages each day, and our customers send slightly more than 3.3 million messages each day (taking all services together, mailing lists, newsletters, etc.).

All our web servers (all sites and services taken together) receive more than 450 million hits each day and the MySQL servers process in total more than 50,000 requests per second (which means an advance of more than 250% in relation to 2009, probably due in the main to the increased availability of CMS that use a lot of resources, like Wordpress, Joomla and SPIP for example).
