I know that I said that I was going to try to simplify things by getting rid of some hardware. Well it seems like that is not working out as planned.
A couple of days ago, I noticed that all of the network speed that we were getting going to external sites was pretty bad. It would fix itself when I rebooted the Airport Extreme. I noticed that the activity lights on the WAN side of the Airport express were blinking like crazy. I plugged my Linksys WRT54GS router between the cable mode and the Airport, and all of the problems went away. I am not sure if this was happening because the Airport was spending a lot of CPU cycles on filtering traffic, that it was slowing down the outbound traffic, but everything is working now.
Also, yesterday the host running this site was down for several hours. It seems that Tektonic is moving the management of the Unmanaged VPS unixshell#. I am not sure if my VPS will move with this company, or even what the cause of the problems were. But I do have the old server sitting in the garage.
