Looking for ideas on alert for up coming network outages.

Hi,

I'm looking for something visual that will notify users of upcoming carrier network outages. The only thing I can come up with is a Custom HTML with basic text stating that "Circuit XXXXX will be down for 2 hrs on 24 Feb" Has anyone anything better? Ideally I would like something like the custom html that would give you a visual notice of upcoming outages and would automatically send out a reminder e-mail on the day of the outage.

Thanks.
