There was a partial outage of the IEM website between about 7:30 and 8:15 PM on 23 September 2021. A likely innocent web API user sent a few thousand simultaneous requests at a brittle website component that ended up exhausting resources for the Fast-CGI PHP server. I have added some additional code to help monitor this and keep the brittle resource from being overwhelmed. Sorry about the outage and thanks for the patience!
