Dear Atlas users, Today we're going to enable two features that have been forecasted in the January 2013 Atlas update (https://labs.ripe.net/Members/becha/ripe-atlas-january-2013-achievements) Both of these features are intended to prevent runaway measurements which consume system resources, and to limit the resources used by users who don't contribute (any more) to the system; thus they both contribute to the stability and scalability of RIPE Atlas. They are both controlled by the credit system. The first feature is about sending warning emails if someone is about to run out of credits. That is, if the current credit consumption rate (with a two day lookback period) seems to use up all credits of a particular user within the next week or so, then we'll send an email about this. This allows the user to organise some extra credits, or stop some less important measurements in due time. The second feature stops measurements if someone actually runs out of credits. For now we'll use a *warning only* mode -- that is, the process will not actually stop measurements, it will only send emails. After a couple of weeks we'll change this to actually stop (some of the) measurements as well as notify the user. Our tests show that at the moment there are about a dozen people who would see effects of these processes. Both of these are necessary steps towards removing the existing limits imposed by the system (such as maximum amount of probes that can be used). Please let us know if you have questions or concerns, either on this mailing list, or (privately) by sending a mail to atlas@ripe.net Best regards, Robert Kisteleki RIPE Atlas team
