1. Service Details

The CNMC Speed Test service allows you to perform a quality of service test of your connection and to access long-term service quality information in Spain. In this way, you can view current and past quality of service results for data sets across different operator networks by geographic area. To this end, it offers users access to Statistics, a Map, and an Open Data interface.

Please note that certain factors can affect the measurements made by the service, such as radio frequency interference and technical aspects related to the devices used. This means that specific measurements made using the service may not necessarily reflect the correct quality and speed of the measured connection.

The current configuration of the service is not intended to certify or resolve individual issues with internet access service performance.

The results provided by the service are for informational purposes only, as they may be influenced by the user's environment.

When tests are conducted over a mobile network, you should note that the service will send and receive large amounts of data, which are directly proportional to the connection speed being measured. For example, with a connection speed of 100 Mbit/s, the test will transfer approximately 100 megabytes of data. The loop mode will multiply the data consumption by the number of tests performed in a loop. Therefore, it is recommended that your mobile operator's data plan is unlimited or allows for high data consumption without additional cost.

CNMC does not guarantee the reliability of measurement results for connections with speeds above 1 Gbit/s due to measurement restrictions such as device characteristics and browser version, which are exacerbated at higher connection speeds.

2. Limitation of Liability

CNMC makes every effort to ensure that the service is up-to-date, accurate, and complete.

However, you should keep in mind that the service is only a technical aid for informational purposes.

CNMC accepts no responsibility for the timeliness, accuracy, completeness, or quality of the information, nor for any failures that may occur in the service due to errors, inaccuracies, incompatibilities, including minimum storage and memory requirements.

CNMC accepts no responsibility for any damages or losses of any kind resulting from the use of the service.
