You're supposed to put all your devices behind the "Whitebox". Using your solution would give them skewed results, according to their terms:

The Whitebox should be placed in between your existing router and your networked computers. Any devices that connected via ethernet cable to your existing router should instead connect to the Whitebox. This ensures that the SamKnows device is always aware of the network being used and will never run tests at a time when you require your full bandwidth to be available. (Whitebox faq)

The problem of factoring a large number is hard when it's a semiprime where both factors are very large numbers around the same magnitude as the square root of the semiprime. In this case 191605050401140404051920181528 can be factored into 2^3 * 3 * 23 * 222647 * 694079 * 8335727 * 269462689 which is easy to factor as the one but largest factor is only ~= 8 million. A naive program that just divides by 2 and all odd numbers up to 8335727 can give you the answer in less than a minute on a moderate computer nowadays. After finding the 8335727 factor you know that you will not have any more factors in 269462689 since sqrt(269462689) ~= 16415 which is the largest divisor you'd have to try to factor it.

Don't click the 'Get certificate' button. Once you click 'Add exception' and the pop-up is shown, Firefox is already retrieving the certificate. When it has retrieved the certificate, the 'Permanently store this exception' box is checked. If you click, 'Get certificate', the process starts over again. So what happens is that you uncheck the 'Permanently' checkbox and the 'Get certificate' process will re-check it again just before your click on the 'Confirm' button is processed. Indeed, very annoying.

63 servers * 48 disk of 1 TB = 3024 TB. According to the announcement on the archive.org 3 Petabytes would be right.
