School wifi down

So today we were supposed to do computer testing but the wifi was down till 9 ish so it was postponed what’s great however the people who are not toning to test today were told they don’t have to come in till like 9:30 or something like that but since the wifi came back on we started class earlier than we planned but not all the students were at school yet so they are making them absent in class and tarty to school
