Was this all done at iStop's request and with their full support?
When iStop's router stopped making BGP announcements to the world (because its last transit link was cut), and ISP3 highjacked the IP blocks and made BGP announcements pointing to ISP2, I don't think there was much of iStop left to complain, and it was to the benefit of end users, so this highjacking was not nefarious. Either ISP2 was asleep at the switch and let this happen, or perhaps they had a deal ith iStop that they would not do BGP until block of IPs was transfered, so they got a friend at ISP3 to do the deed for them. The transfer of IP to ISP2 happened shortly after that day, after which ISP2 did the proper BGP announcements for IPs now assigned to it.
