I emailed them about the souvenir just out of curiosity. This is the response I received.
"You may notice that we have temporarily turned off some minor site functionality to increase server performance, including log avatars and find counts. Likewise the International Geocaching Day souvenir will be awarded retroactively once we have the servers performing as expected.
As we are addressing several large issues that occurred over the weekend, we understand that this email may not completely or directly answer your specific query. If you need additional help or information, or we did not address your query, please reply.
Again we apologize for any inconvenience or frustrations these issues may have caused and will have site functionality restored as soon as possible."
Great customer service as always. Just gotta be patient.
