We are switching from at&t to Comcast ISP. When we switch what to I need to keep in mind? What pitfalls should I be aware of?.
We host our own website
Our domains are registered though a separate service (not through our ISP)
All traffic comes in to a router then a Firewall then to our network
Email filtering is hosted by a separate service, we use exchange 2010 once we receive it
Thank you in advance
