Names changed but date/time real ;)

Bobs Deals has a business internet connection (static etc) with ThatISPThere Inc.

Bob gets an email from ThatISPThere Inc today at 12.30pm advising there will be an IP change on the connection.

Date : 13th June

Time : Between 12am and 6pm

Thats right. Not even 24hrs notice. Not even a real time window. 

Advised Bob to go back and say "hell no, IT needs the time its happening so can switch over IP in routers/firewalls etc and Im not paying them to sit around for 18 hours waiting"

Be interesting to see their response......
