Currently (2019-10-13 3:50 AM KST) there's a service outage of calculating "Today's pathes" for items because it seems there's unknown fault of VM server locates at KT datacenter. Other services are all good. We're trying to restore it but it looks it takes hours because they are also under PM today. :-( Sorry for this inconvenience.
EDIT: 2019-10-13 7:45 AM KST, the server is restored successfully but it seems it requires 1 ~ 2 hours more for DB sync. Meanwhile the result of today pathes could be one based on old data.
