Like so many program bugs the error was quite silly and easy to fix once spotted.
Yesterday I was alerted by Uptime Robot that croquetscores.com had gone down for the first time since moving to Azure December 2014. A simple reboot of the server resolved the problem. The logs showed that the server's CPU usage had been sitting at 98% for the past two hours. Early January I saw CPU usage spikes but they went away and I hoped the same would be true this time. Not to be. Chris Clarke alerted me last night the croquetscores.com was slow, thank you Chris. So another quick reboot to resolve the issue but I knew I would have to look into it further this morning. Sure enough this morning the site was sluggish and CPU usage was sitting in high 90% band. It is usually at 5-8% usage.
Tim Murphy, the owner and developer of croquetscores.com, and the World Croquet Federation have today reached a 12 month co-operative agreement regarding the website. The WCF will pay the annual hosting costs of croquetscores.com in return for Tim Murphy continuing to evolve the results website for the good of the game.
