Our support team received a call from a customer complaining that their next generation firewall (NGFW) was intermittently blocking access to their new voting website. As we were in the process of making firewall changes inside their environment and are responsible for the management of their network they turned to us for help.
The website was a vanity domain hosted at GoDaddy that redirected users to a deep link within another website. We accessed the site and confirmed that it was working properly and sending a 301 redirect as expected, it worked properly both inside their and our environment. We reviewed the firewall logs and found no indications that traffic was blocked by any firewall or IPS. The customer insisted that there was an intermittent problem accessing the website that seemed to affect some users at random.
