Today, most of our colleagues started to work again after well deserved holidays. Unfortunately, Maastricht University (UM) was hit by a serious cyberattack before Christmas. Despite a number of limitations, many activities could continue after the Christmas break without major problems. Some of our colleagues had to forego their Christmas break and (literally) work day and night. Others have sacrificed part of their vacation voluntarily to help. A big word of thanks to everyone for all their support, understanding, compassion, patience and of course the extra hours worked.
