Hello Carsten Schiefner, Good point! I am planning to run 30 traceroutes + dns from 90 (starlink) + 90 (terrestrial) probes for a period of a month. It would come around 15-20M credits per day. So, in total around 450-600M credits would be used. Best regards, Rohan From: Carsten Schiefner <carsten@schiefner.de> Date: Thursday, 14.

Could you please guesstimate your need, so that donors would neither over- nor underspend? Thanks, best - and good luck and success! -C.

Hi Rohan, then you should be sufficiently supplied for now, taking into account what in particular has come your way from Serhii and Fadloe. Certainly happy though to step in if there is additional need by you or, of course, by anybody else for another research project. Cheers, -C. Am 14.

Hi Rohan,
interesting stuff indeed, you’re researching on!
Could you please guesstimate your need, so that donors would neither over- nor underspend?
Thanks, best - and good luck and success!

Yes, this should be sufficient for now. Thanks to everyone who has chipped in. :) Best regards, Rohan From: Carsten Schiefner <carsten@schiefner.de> Date: Thursday, 14.
