This is my new project, please try it & share with your circles if you like it!

It is a website monitoring service that will help you to keep track of your site's outages or modifications. Really useful to quickly react to any uptime issues and to early detect unwanted changes, e.g. if your site has been defaced, if someone is injecting malicious js code or if because of a DB error the prices at your shop show as $0 for every single product.

It is free for the basic service (HTTP or PING check every 15 minutes) that should suffice for many people out there. The other plans are so cheap that are a no-brainer if you need to monitor more than one site, smaller intervals, track changes or be sure your site is reachable from 4 different continents (and more coming).

The whole site works only on HTTPS and we don't store or even process your credit card as it's all done through Paypal.

If you ever need a monitoring system this is the one that will suit most of your needs for a ridiculous price.
 
We've just launched our global monitoring solution!

Our network covers 4 different continents, monitoring your sites 24x7 from New York, Chicago, San Francisco, Virginia, Amsterdam, Sydney and Hong Kong.

Wow... amazon.com is completely disregarding the initial TCP congestion window: it looks like their servers simply pumping as much data as they can, with an aggressive retransmit timeout as well...

See wireshark capture below: no client ACK's have been sent following the initial GET request for the homepage, and Amazon servers are just pumping bytes: ~76KB outstanding, and growing! 

I guess that's one way to make your site faster... =/

Do you REALLY trust all the CAs that your browser trusts? have you ever checked that list?

It's amazing how powerful nginx is. Do you, as NetSec Engineers or Admins, use nginx as a reverse proxy or as a load balancer? It could be interesting to read someone's opinion on nginx vs commercial solutions as F5 LTM, Alteon, Brocade or the good old Cisco CSS.

Love it! How come no one created this before? And they say you can find anything on the Internet... Not until now! :-)

It was giving a 404 for me as well, but I tried from the desktop. I think Google just had some problems with the quality check of the deployment :)

For all the NetSec people out there, it is worth learning some scripting language to make your life easier. Take the effort as an investment, the return is impressive ;-)
 
I found a nice collection of examples to use python for pen-testing and more.
Found it quite stunning how easy it is with python to build "violent" scripts and learnt a lot reading them.

Story
Introduction
Hello everybody!

Welcome to my G+ profile page. I'm Pedro J. Pérez, a guy from Barcelona that lives in Reading.

My interests are all around technology. Mainly mobile phones, networking, infosec and some coding too :)

I work as a network security administrator but I also do some amateur-ish coding in my free time. So if I have you in my circles there's a 90% of probability that you're a coder or a network admin ;-) or write about one of those topics.

Feel free to browse around all my public information and don't forget to visit my pet projects (links in "Contributor to").
