Understanding the limits of simultaneous connections to MySQL / MariaDB
This guide details the restrictions on the number of simultaneous connections allowed on MySQL databases for web hosting.
Simultaneous MySQL connection thresholds
To maintain server stability, security, and responsiveness for all users, the system enforces limits on simultaneous connections.
For each database user at Infomaniak, the limit is set to 38 simultaneous MySQL connections.
This quota prevents shared resource saturation. If this threshold is exceeded, access is temporarily blocked, and errors such as User has already more than 'max_user_connections' active connections or Too many connections may appear.
In practice, this threshold is rarely reached. If necessary, it is entirely possible to distribute the load by creating distinct MySQL users for the various scripts or services of your site.
No hourly connection quota
Infomaniak imposes no restrictions on the volume of queries per hour. Parameters such as MAX_QUERIES_PER_HOUR or MAX_CONNECTIONS_PER_HOUR are not enabled.
Unlike some competing offers, you will not encounter resource exhaustion errors of type SQL Error : 1226 related to hourly activity volume.
