A few technical details on how I’m implementing global load balancing to improve the availability of Machine Learning for Kids.
This wasn’t a great week for Machine Learning for Kids. I think the site was unavailable for a couple of days in total this week, spread across a few outages – the worst one lasting over twelve hours. I know I’ve lost some users as a result – a few teachers / coding group leaders did email me to say (not at all unreasonably) that they can’t use a tool that they can’t rely on.
I wrote in my last post that I would be making changes to prevent this sort of thing from happening again. Now that I’ve done it, I thought it’d be good to share a few details on how I did it.
