Earlier while analyzing a Linux server it was pointed out to me that the Apache logs were filling up with constant connections requesting domains that were not configured on the server. To me it looked as if a load balancer somewhere was misconfigured and sending traffic to our IP address by mistake but I needed to open a ticket with the colocation provider to have them look into the issue further since the network in this case is not something I have any control over. Below is a quick Linux command that will output a list of IP addresses making port 80 connections to your server.

They were left IDLE, never closed, and eventually used up all of the possible connections (which totaled 100) configured in the  postgresql.conf configuration file. In the process of troubleshooting I noticed a bunch of Postgres log entries that I was unable to immediately pin down to what was causing the entries.

Recently I did some research on purchasing a toll free number for a project I was working on. I figured it might be useful to others to provide a short list of the options I came across and some of the details. One thing that was important during this search was the fact that the toll free number had to allow multiple connections. I describe in this article the need for this if you are curious for my reasoning.

Below is a list of some of the companies I researched and information regarding a package they offer. Information listed will include website/sales contact, the monthly cost, minutes included in the plan, the per minute charge after the initial minutes are used, and the number of connections if I was able to get that information easily.
