External websites that make use of Blizzard’s StarCraft II ladder API are unable to retrieve the current data for the KR server. This is the case for Sc2ReplayStats and a website used to view the current MMR boundaries for multiple melee formats.
I created a thread in the StarCraft II API forum category 19 days ago, but I am not sure if it received any visibility from developers, so I’m creating a thread here as well to bring it to your attention.
Thanks,

Edit: Since I was unable to include links in this post, you can find Sc2ReplayStats by googling “Sc2ReplayStats” and find the MMR ranges website by googling “sc2 ladder ranges”.
