It was a crazy weekend for a lot of people I work with because of this. That pump has been running constantly for like 5 years in an extreme environment so it's pretty impressive that it ran that long. However this was a pretty major failure for any spacecraft to have. Fortunatley there is enough redundancy built into the space station that the impacts were fairly minimal and there is a spare on orbit so the crew can swap out the failed pump.
They will be doing 2 spacewalks to replace them pump package, the first of them is planned for Saturday.
