what i suggest is to get the CTO to talk to 1/2 customers in each area who are online most of the time. get him to agree to allow CTO's pings to his PC so that CTOs can check for network condition in that area.for example i come almost at the last switch of my network. if my cto pings me and i allow him to ping me, he can be sure that network in entire sec-6 of panchkula is working...my first CTO used to do like this.
