In Brazil this change was indeed noticed by smaller network operators. Most
provided either 8.8.* as DNS to their customers or used as forwarders in
their own DNS resolvers, as 8.8.* was usually good, but that changed at
exactly the time shown in your analysis.

Before this change, most of the time 8.8* was answered from Sao Paulo.
