Critical Thinking Question $-$ Acme Company uses a firewall to limit the websites accessible by employees from the Acme local area network. All websites are accessible by default unless Acme decides to block them for a specific reason. One month ago, the Acme CEO decided to block the website of a local sandwich shop $($www$.$TheGoose.com$)$ due to competition against the Acme on$-$site cafeteria.

The Acme IT department immediately used nslookup to determine the IP address of the website and added the following firewall rules accordingly: DENY $75\mathrm{.}119\mathrm{.}206\mathrm{.}168$ TCP $80-$and$-$ DENY $75\mathrm{.}119\mathrm{.}206\mathrm{.}168$ TCP $443.$ The firewall successfully blocked the website starting one month ago and this functioned as$-$desired up until last week. Users are currently able to access the website www$.$TheGoose.com much to the CEO$$s dissatisfaction. No other malfunctions have been reported on the network, other websites load fine, and other blocked websites remain inaccessible.

Of the options below, what is the MOST LIKELY reason employees are now able to access www$.$TheGoose.com $?$
