I think this would be a good idea. I've actually been considering

something like this for my tools. My idea was to use multiple files. One
would be for issues that would affect every tool, like if the webserver
was going to be down. Others would be for issues that may only affect a
couple tools, like one of the DB-servers being down, or high replag on a
server. That way tools that don't need DB access or aren't significantly
affected by high replag won't have unnecessary notices but the tools
that do need it can still have the notice.
