It is time for my organization to begin evaluating carriers again for data communication services. We have historically had a private global managed service frame-relay network using one of the large carriers. We are expecting to change technologies at this time and want to consider other carriers and their services. What experiences have you encountered with the following carriers/service providers and what technologies (MPLS, private VPN, frame relay, etc.) are you using? What would you recommend to an organization about to go through a network migration?
The carriers/service providers we are considering are:
Savvis
Equant
AT&T
MCI
Virtela
The emphasis at this time needs to be on GLOBAL (US, Canada, Mexico, UK, China, Taiwan, Thailand, Singapore) and on managed services. We do not have the skilled staff necessary to manage these services. So, we depend on managed services to ensure change management, reliability & uptime.
Thanks for your assistance.
