Let that be a lesson to all, that those who base their business model around a third party are doomed to fail... In Fring's business plan, I'm sure one of the single points of failure is the fact that at any time, Skype can choose to put them out of business by adding one or two lines of iptables filter rules to their firewall.
They should do what skype does, not attempt to piggy-back on skype. It doesn't work, because eventually your business will actually grow, and then what happens is skype becomes your competitor, rather than your friend. Once this happens, it becomes in their best interest to remove you from the equation.
I worked for AT&T in several parts of the country on their core networks, and in the early 2000's they had misconfigured all of their Solaris boxes and I worked with the infrastructure group to implement a startup script on Solaris to tune all the ndd settings for performance. The problem with Solaris is that by default all the TCP, UDP, Ethernet, etc settings are set for a Desktop workstation, not a server. Most system admins know to tune these settings, otherwise in a lot of cases a multi-CPU box will perform as slow as a 1 CPU box. Anyway, at specific companies I worked with (AT&T Broadband / Worldnet in St. Charles, MO was one big one), all the servers were configured without the proper settings for a server, so we had all kinds of issues as a result, a big one is that the tcp accept queue is not set high enough and so connections to daemons will drop after a low number of connections, making it appear that the box can't handle the connections...., As a result, they had spent millions on numerous servers (in one situation they had over twenty 12-cpu servers just for smtp...
These changes seem small, however, changing "ndd" kernel parameters on a Solaris box is not a single task, it is an infrastructure-wide task, and therefore requires the coordination of dozens of different groups, it really took a long long time to get this script implemented. It was called "S99nddfix" and it had all the ndd tunable parameters in it. Later when I worked at a different AT&T group in a different state, I noticed my script had been implemented on all the Solaris servers in the 200+ server environment.
