BIND : DNS Issue #1
Q:
Why do I get errors like "dns_zone_load: zone foo/IN: loading master file bar: ran out of space"?
A:
This is often caused by TXT records with missing close quotes. Check that all TXT records containing quoted strings have both open and close quotes.

Tier 1 / Tier 2 / Tier 3 / Tier 4 Data Center
Q. What is data center tiers? What is tier 1 data center? Which tier / level is the best for maximum uptime?
A. Tier 1 to 4 data center is nothing but a standardized methodology used to define uptime of data center. This is useful for measuring:a) Data center performance
b) Investment
c) ROI (return on investment)Tier 4 data center considered as most robust and less prone to failures. Tier 4 is designed to host mission critical servers and computer systems, with fully redundant subsystems (cooling, power, network links, storage etc) and compartmentalized security zones controlled by biometric access controls methods. Naturally, the simplest is a Tier 1 data center used by small business or shops.
The levels also describes the availability of data from the hardware at a location as follows:

- Tier 1 = Non-redundant capacity components (single uplink and servers).
- Tier 2 = Tier 1 + Redundant capacity components.
- Tier 3 = Tier 1 + Tier 2 + Dual-powered equipments and multiple uplinks.
- Tier 4 = Tier 1 + Tier 2 + Tier 3 + all components are fully fault-tolerant including uplinks, storage, chillers, HVAC systems, servers etc. Everything is dual-powered.
Data Center Availability According To Tiers
The levels also describes the availability of data from the hardware at a location as follows:
- Tier 1: Guaranteeing 99.671% availability.
- Tier 2: Guaranteeing 99.741% availability.
- Tier 3: Guaranteeing 99.982% availability.
- Tier 4: Guaranteeing 99.995% availability.

IPV6 - Launch 6.6.2012
THE FUTURE IS FOREVER
6 JUNE 2012
Major Internet service providers (ISPs), home networking equipment manufacturers, and web companies around the world are coming together to permanently enable IPv6 for their products and services by 6 June 2012.
Organized by the Internet Society, and building on the successful one-day World IPv6 Day event held on 8 June 2011, World IPv6 Launch represents a major milestone in the global deployment of IPv6. As the successor to the current Internet Protocol, IPv4, IPv6 is critical to the Internet's continued growth as a platform for innovation and economic development.

System Administrator Appreciation Day
July 29, 2011(Last Friday Of July)
12th Annual
System Administrator Appreciation Day
A sysadmin unpacked the server for this website from its box, installed an operating system, patched it for security, made sure the power and air conditioning was working in the server room, monitored it for stability, set up the software, and kept backups in case anything went wrong. All to serve this webpage.
A sysadmin installed the routers, laid the cables, configured the networks, set up the firewalls, and watched and guided the traffic for each hop of the network that runs over copper, fiber optic glass, and even the air itself to bring the Internet to your computer. All to make sure the webpage found its way from the server to your computer.
A sysadmin makes sure your network connection is safe, secure, open, and working. A sysadmin makes sure your computer is working in a healthy way on a healthy network. A sysadmin takes backups to guard against disaster both human and otherwise, holds the gates against security threats and crackers, and keeps the printers going no matter how many copies of the tax code someone from Accounting prints out.
A sysadmin worries about spam, viruses, spyware, but also power outages, fires and floods.
When the email server goes down at 2 AM on a Sunday, your sysadmin is paged, wakes up, and goes to work.
A sysadmin is a professional, who plans, worries, hacks, fixes, pushes, advocates, protects and creates good computer networks, to get you your data, to help you do work -- to bring the potential of computing ever closer to reality.
So if you can read this, thank your sysadmin -- and know he or she is only one of dozens or possibly hundreds whose work brings you the email from your aunt on the West Coast, the instant message from your son at college, the free phone call from the friend in Australia, and this webpage.

World IPV6 Day - 8 June 2011
ABOUT WORLD IPV6 DAY
On 8 June, 2011, Google, Facebook, Yahoo!, Akamai and Limelight Networks will be amongst some of the major organisations that will offer their content over IPv6 for a 24-hour “test flight”. The goal of the Test Flight Day is to motivate organizations across the industry – Internet service providers, hardware makers, operating system vendors and web companies – to prepare their services for IPv6 to ensure a successful transition as IPv4 addresses run out.

What is VPLS?
Virtual Private Networks have evolved considerably. Today, VPLS-based VPNs enable service providers to offer enterprise customers the operational cost benefits of Ethernet with the predictable Quality-of-Service characteristics of MPLS. This movie gives a clear introduction to VPLS.

Cloud Computing
What's Cloud Computing?
Cloud computing is an idea that what makes up your "personal computer" - your desktop, your apps, and your data, - can live and run on the Internet instead of on your hard drive.
With our "Cloud" operating system, users can turn on their computers to a web browser, and immediately start surfing the web, emailing, and chatting. "Cloud" simplifies the experience of using a computer, by moving everyday computing into the web browser.
Cloud can be installed and used together with other operating systems, or can act as a standalone operating system.
