We got an email asking to contact a rep at the Nationwide Arena about the ticket sales and this is what she told me:
The USFSA asked the arena not to sell seats on the judge side yet (she does not know why)

.
She thinks those seats will be eventually on sale either at the time of weekend package sale or individual ticket sale, which will take place later this summer.
The reason why some of us were able to score tickets on the judge side yesterday was there was a technical glitch that allowed us to do so temporarily. I asked her if those who were able to get the tickets on the judge side "by accident" can keep those seats and she said yes.
Honestly I do not know why the USFSA does not want to sell tickets on the judge side to all event ticket buyers, who are really royal figure skating fans - they want to have more people on the opposite side for the broadcasting purpose!?
