Apologies if your viewing pleasure was interrupted, but for some time a certain West Coast university specialising in 'green' issues has been stressing the server with continuous data downloads, at about 17:00 they managed to find a download query that pushed the server into swap.
It took half an hour to shut down the web server and finally the mysql server.
And identify the source of the attack.
It has now been blocked from further malicious access and service is back to normal. Some data may have been lost.
