Hello, We are using ISPConfig 3. We have multiple websites on our server. We have one domain that for some unknown reason, is sometimes unreachable from the outside the server. We can get to it form the inside, but when trying to see it from the WWW, it is unreachable. If we reboot the server, the website availability is returned. Can someone offer any ideas as to what might be wrong, or where one might look for clues? Thanks Joseph
Check the dns zone of that domain with intodns.com, it might be that you have a split brain situation in the dns record where primary and secondary dns contain different zone data.
