The role of the host
The speed of loading a website depends on many factors (server performance, host network infrastructure, visitor Internet connection, website optimization, etc.).
As a host, Infomaniak strives to offer the best in terms of accommodation and constantly evolves its products and infrastructure:
- All hostings work on state-of-the-art SSD drives.
- The infrastructure benefits from more than 70 Gbit/s interconnection and redundancy with Cogent, Level3, etc.
- In order to easily absorb peak traffic, servers run with 64-bit Intel Xeon processors, which are replaced regularly and shared/mutualized servers use on average only 40% of their CPU power.
In addition, when you submit a request for support regarding delays, Infomaniak analyses whether or not...
- ... your hosting server works normally and has not encountered any problems in the last 48 hours.
- ...the network infrastructure has not encountered any disruptions during the last 48 hours.
