Getty/Chip Somodevilla When Amazon started to have technical glitches during Prime Day, it raced to set up a lightweight landing page and cut off international traffic to keep up, according to documents obtained by CNBC. A source told CNBC that the scene was "chaotic" and that 300 people were on the line during an emergency conference call. An internal tool called Sable also reportedly experienced problems, causing problems for other parts of the website. Amazon's servers couldn't handle the flood of traffic from shoppers during Prime Day — and the company cut off all international traffic and launched a backup landing page in an effort to fix the problem, according to internal documents obtained by CNBC. Amazon declined to comment to CNBC and did not immediately respond to request for comment from Business Insider.
