But Tessa Plum are asking for help when they were under attack with a lot
of UDP requests flooding to the servers.

When a patient with flu asking for help, but his doctor only suggest him to
mask himself avoid he inffectiing others. Wearing masks is generally good
for public but not a cure for that patient.

Given 20Gbps attack, not a huge one, I still think sharing the load among
multiple servers make sense. If possible, some advanced anti-ddos
techniques are available.  There is no cost-free solution for DoS.
