Do we have server monitors for those machines? If not, I suggest to use some third party service to monitor the server's uptime and performance, like http://www.siteuptime.com or http://www.elkmonitor.com/. I guess there are some free service provider available.
You might want to look at http://meta.wikimedia.org/wiki/Wikimedia_servers and links therefrom; there's also a load of stuff at http://meta.wikimedia.org/wiki/Statistics In short, yes, there's all sorts of monitoring going on to see which machines are doing what and how well.
As for being able to access some wikis and not others, I don't think the servers are divided like that, so I'd say it must have been either a) coincidence, b) some odd side-effect of different load on the actual databases or c) some transitory problem with the settings that meant some addresses were pointing to the wrong place or somesuch.
