Ponca City, We love you writes "When Google started, it would only update its index every four months. Then, around 2000, it started indexing every month in a process called the 'Google dance' that took a week to 10 days and would provide different results when searching for the same term from different Google data centers. Now PC World reports that Google has introduced a new web indexing system called Caffeine, which delivers results that are closer to 'live' by analyzing the web in small portions and updating the index on a continuous basis. 'Caffeine lets us index web pages on an enormous scale,' writes Carrie Grimes on the official Google Blog. 'Caffeine takes up nearly 100 million gigabytes of storage in one database and adds new information at a rate of hundreds of thousands of gigabytes per day.' Now not only does Caffeine provide results that are 50% fresher than Google's last index, adds Grimes, but the new search index provides a robust foundation that will make it possible for Google to build a faster and more comprehensive search engine that scales with the growth of information online."

Two of these Personal Rapid Transit (PRT) systems are being installed this year, one at Heathrow International Airport, near London, and one in the United Arab Emirates, where it will be the primary source of transportation in Masdar City, a development that will eventually accommodate 50,000 people and 1,500 businesses and is designed to emit no carbon dioxide. The article examines these two systems and includes video that includes an animation of the PRT system in action."

Their website is down, and there have been no announcements from either HavenCo or Sealand. HavenCo has been covered here before; it was mostly known for offering hosting of content that might be illegal in other countries. Does anyone have news about what happened to them?"

David Gerard passes along a posting on Google's official blog announcing that they have extended the three-nines SLA for the Premier Edition of Google Apps from Gmail alone to also cover the Calendar, Docs, Sites, and Google Talk services. 99.9% uptime translates to 45 minutes a month of downtime, and the blog post puts this in context with Gmail's historical reliability, which has been between three and four times as good over the last year (10-15 min./mo.). It also claims, based on research by an outside group, that Gmail's historical reliability beats that of in-house hosted solutions such as Groupwise and Exchange, on average. Reader Ian Lamont adds an article in The Standard that digs down into the details of the SLA, revealing for instance that outages of less than 10 minutes aren't counted against the monthly 45 minutes.
