Dear RIPE Atlas users, We'd like to inform you about an upcoming change affecting downloads of large, historical results. As of today, one can ask the RIPE Atlas API to supply results of measurements without time boundaries, as in "give me all the data you have for this measurement". That's fine for results of one-off measurements because those are always relatively small. However for periodic measurements this is mostly harmful as it results in possibly huge amounts of data, as such it's often aborted, and incurs costs on both parties. We plan to enforce time limit parameters, where the query for results will have to specify a start and and end time and the interval spans at most a week. Scripts that intend to download results for a wide time interval will need to loop through the interval in chunks (perhaps per day, ideally aligned to UTC midnight to be the most efficient). UI functionality will not be affected. We intend to apply this change around the first week of August. Regards, Robert Kisteleki, for the RIPE Atlas team
