Content Delivery Network or CDN is the next tip to speed up your website. There are many reasons, but the main one has to be with your machine. Depending on the browser, you may have one or multiple threads requesting HTTP objects in parallel. I read someone else, that Chrome has a 6 thread limit (I am not sure, but bear with me, it is a small number). Additionally, a web server that hosts everything generally does it in a FIFO way, the first request is the first attended. So, so far there are two bottlenecks we need to get rid of.
To show you I will use my business website https://okay.network and I will use Google PageSpeed Insights as the metric.

If you have installed FusionPBX from the installation scripts you will notice it has already some fail2ban configurations. If you are using my RPM's, it doe not include any kind of this configuration as my philosophy is to specialize in the package to do one thing, not a do-it-all. Anyway, if you are only using FusionPBX with FreeSWITCH as a personal PBX those rules should be more than enough.
I recommend you do a quick reading of my previous fail2ban post where I describe the gap between Layer 7 exposures versus Layer 3 controls. You will understand my thinking.
If you are being more serious about your PBX or you are running a business you will find at one point those rules are not enough. I will explain myself a little more. As a commercial service, your exposure to the world is bigger; your domain is advertised, telephones do DNS, HTTP and SIP request to your servers and sooner than later you will start getting your first kiddy scripts targeting your servers. As you grow, you will find your customers are far to be technical; they do many dumb things (wrong password because they changed something on the service or inside jobs from tech staff are some examples) which leads to fail2ban rule applications.
There is nothing more harmful than a bad review from an ignorant customer. They do not know why they are being blocked. So, here is where we need to tun fail2ban and add some important information to pre-block offending IP's.

For a long time, I have been working on the Billing/LCR for FusionPBX in-app software.
The LCR software has the main objective to help you to save money by selecting automatically the cheapest route depending on your destination. However, LCR is more than that. LCR allows you having smart fault tolerance, it will always try the first best option, then the second-best option which is not always the same.
The BIlling software allows you to bill for your PBX use. You will be able to bill by the minute, by the call or a combination of both. It also allows you to deal with different currencies and
I am very proud to present version 1.2.2 with the following outstanding changes.
Before I forget, you can download it from OKay's download area, or if you are a CentOS user, you can get the RPMs which it does the installation process really easy.
