We have monitoring the MDS service and have not seen any additional issues during the day.
The incident that started last night was triggered by a Java out of memory problem, an error that we have seen rarely in the past (1-2x times a year). We are working on deploying a redundant MDS system, which should prevent these kinds of problems in the future.
