Blogging In Transition: A Host Of Issues – Act Three

There’s nothing like your site going down routinely to lend a sense of urgency to the search for an alternative hosting solution. While my circumstance was not quite as dire as that pictured right, it certainly felt similar.

The newly live server at VPS.NET was crashing at least once every day or two, but it remained live while I poked around the TKL web site investigating the other hosting providers that had partnered with the project. The biggest was Amazon’s EC2, but recent events lead me to shy away from Amazon for my own purposes.

Blogging In Transition: A Host Of Issues – Act Two

Welcome to act two of our little saga, whereupon our protagonist, having found that his existing shared blog host is now unreliable, has set out in search of a new host. A private host. Very possibly a virtual host. In fact, the situation has become very cloudy indeed.

In some regards the growth of a blog such as this, and the related hosting issues, is a little like being a teenager. Living at your parents home is very cheap, but you’re limited in what you can do, and the sort of traffic that they will allow. Ultimately your desire for freedom will force you to find your own place to live, where you have greater control of what goes on, even if that means you always have to clean up after yourself.

The decision to seek a more private host is only one step in this migratory process. The next question that arises is, “what kind of host?” Windows? Linux? If Linux, what distribution? Which supporting applications? How much CPU, memory, storage, etc?

Blogging In Transition: A Host Of Issues – Act One

In the three years since it began this blog has been through a number of transitions. The most recent being just a few weeks ago. This is a little tale of that experience, offered to help anyone else who might be following a similar path. This little drama comes in the form of three acts. In this first act we examine the history of the site that lead up to recent events.

My efforts at blogging began in fall of 2007 on the free hosting at WordPress.com. While a fine place to get started I eventually wanted to tweak WordPress beyond the scope that was allowed on that service. In particular, the desire to include more multimedia content provided the motivation to move the site to a paid host.

VUC Video Calls: A Two Act Play

As many of you may know I’ve been trying to put together a video call for the VUC over the past few months. After a lot of thought, but little action, act one of this little project will get underway this coming Friday, August 13th at 1pm EDT.

The basic idea for the project has been with me for a year, ever since I trialed the Polycom VVX-1500 video phones last summer. It evolved as I was later asked to research video conferencing systems for my employer, a project which was eventually tabled in Q4/09.

There are quite a number of factors to consider when you’re thinking about implementing a video conference solution. At its most basic I needed in some substantive way to grasp the difference between one-to-one video calling using desk phone, traditional video conferencing and “Telepresence.”

Evolving The Mobile Data Billing Model

AT&T 3G USB Dongle Earlier this week AT&T has its quarterly earnings call. Normally I would not give it any notice at all. It’d just be another bunch of noise in my Google Reader in-box. This week they did something that simply jumped out at me; they called for an evolution of the current billing model for mobile data plans. Oddly enough…I agree…sort of.

Of course, their perspective on this is not quite the same as my own. AT&T want to be rid of the $60/mo for all-you-can-eat billing model and charge based upon actual usage, perhaps in some sort of tiered fashion.

Literally everyone knows that the current billing model is badly broken. Their flat rate “unlimited” plans are not really unlimited at all. My Sprint 3G service was pretty plain about it being capped at 5 GB/month. Beyond that I’d guess that it gets costly. Moreover they claim performance levels that almost no-one ever achieves in practice.

Amazon Responds About SIP Attacks From EC2

On April 18th Amazon finally responded publicly with respect to the SIP attacks recently suffered from hosts within their EC2 service. Their response comes in the form of an informational security bulletin posted to their AWS Security Center.

There have been some recent discussions about SIP brute force attacks originating from Amazon EC2. We can confirm that several users reported SIP brute force attacks originating from a small number of Amazon EC2 instances about a week ago. It appears these attacks were designed to exploit security vulnerabilities in the SIP protocol. There is nothing specific about this attack that requires Amazon EC2. It was a brute force attack that could be launched from any computer on any network.
