From SportyHQ:

Many of you have commented or sent an email asking what was going on with the rankings this past weekend as you noticed some very unusual fluctuations. SportyHQ was running an update program to correct the instances when a member wasn’t assigned an initial ranking. When first launched the program has a self ranking program in place, but it was very tough for people to correctly gauge their skill level accurately which led to further problems. Currently the club administrators for each club can set an initial ranking for players within the first 2 weeks of joining. However there are some clubs that don’t have a professional, or somebody to intake new players. As players played more matches, and didn’t have a ranking, it became a bigger problem.

This past weekend SportyHQ ran an update to initialize those without a ranking. Because of the huge amounts of data being crunched, you would likely have seen your ranking jump up and down a few times on the weekend. They have completed this now, and for 90% of people, there was a slight deflationary outcome to their ranking. Don’t fear, the algorithm hasn’t changed, nor were any results manipulated. It was simply a system wide update. Hope this helps people understand what was going on this weekend. Should you have questions, you can contact the Squash BC Office.
