Known issue with client webserver

This morning it was brought to our attention that the majority of our clients' websites are redirecting to our webmail site.  What normally happens is that we run multiple sites on one webserver, and a special configuration file re-directs clients to the correct site based on the address they type in.  It seems that this file has been corrupted somehow, and though we have a recent backup, we will not be able to address the issue until later today.  Please bear with us, and the situation will be corrected as soon as humanly possible.

EDIT: we were able to correct the majority of sites within an hour of the first post - at this point all sites are directing properly to their respective domains.  We will continue to monitor, and thank you for your understanding.
