EETT provides all measurement data from HYPERION to the public for free. The data include measurements from both registered and anonymous users, and have been adequately processed so as not to contain any personal information (user IP address and location information). The user can select the time period of interest and download the data in CSV format. The data are encoded in UTF-8 format and also contain greek characters. They can be freely reused by any interested party (e.g. ISPs, researchers, or even simple users).
DISCLAIMER: EETT cannot guarantee the absolute correctness of the data and the accuracy or representativeness of the measurements, since the measurements are conducted and metadata are generated based on the information provided by the users themselves.
