Limits listed below are automatically enforced by the MySQL server. The limits are there to prevent single users/customers from over-loading MySQL for other customers, and we do not reset these manually.
MariaDB and Percona are MySQL variant, and can be used by nearly all software that can use MySQL.
All database servers offer encrypted connections ("SSL") with minimum TLS v1.2.

1. Storage space
Storage space is limited by the size of your web hotel, and is counted as the sum of files and databases, including metadata/indexes. Example: if you have a 10 GB webhotel, and use 6 GB for files, you may only use 4 GB for databases.
2. MySQL limits
If these limits are exceeded, the MySQL server will reject further logins/queries.
See below for brief explanations of each limit. Connections from webhotel means from webhotels hosted on our webservers. External connections are all connections that are not made via IPv6 from our webservers.
Limits per hour are based on the number of relevant commands sent within the past hour. Example: if you reach the limit within five minutes, you must wait for around 55 minutes before it's possible to perform the same type of command again. See also the MySQL documentation for more information.
3. Explanations of each maximum limit
- the number of simultaneous connections
- the number of connections per hour
- the number of changes in data, tables or database per hour
- the number of queries or commands per hour
4. Connection limits
If these limits are exceeded, the MySQL server will reject further connections.
If you e.g. from an external IP address attempt to connect 6 times within 5 seconds, the 6th connection will be refused. The error message may look like "connection refused" or "unable to connect to remote host", depending on what software you use to connect.
"External" connections are all connections that are not made from our IPv6 addresses. IPv6 is the default for communication from webhotels hosted by us, unless IPv6 is unavailable for the target service.
