At some point during the night an issue with our main DNS server cause Apache to stop working properly on mail.lewiscounty.com which handles Openwebmail for our mail server. This has been corrected.
It also appears that our monitoring system is also offline this morning. I am headed to the office to manually restart it. Normally I would have caught a cascade failure like this.
For some reason mail.lewiscounty.com had only one DNS server conigured. This has also been corrected. This shouldn't happen again.
