What is happening next month?

Question 65 - 67 refer to following paragraph:W: Did you hear about the network closures next week?
M: Mr. Bronson got the email about this yesterday. (65) They need to upgrade our network so we can update our software next month.
W: Oh, Ok. But (66) why would they put the 2nd floor offline at one o’clock? They are usually so busy during that period. I don’t understand why they would schedule it like that. They should do it on their lunch break.
M: Hmm…(67) Good point. You should go to talk to the manager. I’m sure he will agree with you, and then he can get the schedule changed.
W: Yeah, I will. I think I better tell him now so we can arrange it.
