Different Internet service providers

[Francisco Neira Basso <fneira () defensoria gob pe>]

Hi all,

I am trying to defend my point about the following:
To have real redundancy with our Internet access it is necessary to have 
2 different ISPs.

At the moment, we have two providers, one with a fiberoptic last mile 
and the other with microwave link. Obviously they also have different 
networks and points of presence.

One of the providers is arguing and willing to sell us _both_ accesses 
and I want to backup my point with additional arguments.

Is there a written standard such as 17799 or 27001 that recommends 
different ISPs in order to enhance the business continuity?

Thanks in advance for yuor replies and comments.

Regards,
