Why is there so many maintanance been conduced? Your reducing amount of available days per month with internet and within last month you have had 3-4 maintanance days. Can't you do it all in 1 day?
Service maintenance are usually scheduled during off peak time however, there are situations that an immediate maintenance is needed to ensure continued performance on the network. Could you shoot us a PM with your details to better understand situation and get to the bottom of this.
