We posted last Friday about the Tweets-per-second (TPS) counts we saw during the first week of the World Cup and the record TPS seen at the end of the NBA Championship game. The second week of the World Cup continued to see consistent spikes in TPS after goals that are remarkable increases over our average of 750 TPS. However, we caution to call any goals a record this week both because many of the games were played simultaneously with another one and total numbers were fairly similar to the first week when only one game was being played at a time.

However, we are calling the end of Japan's 3-1 victory over Denmark a record that bests the end of the Los Angeles Laker victory over the Boston Celtics (3,085 TPS). When the referee blew the final whistle, we saw 3,283 TPS. (The Netherlands/Cameroon game ended six minutes earlier.)

Early in 2009, when Twitter employed less than 50 people, we faced two different security incidents that impacted a small number of users. Put simply, we were the victim of an attack and user accounts were improperly accessed. There were 45 accounts accessed in a January incident and 10 that April for short periods of time. In the first incident, unauthorized joke tweets were made from nine accounts and attackers may have accessed nonpublic information such as email addresses and mobile phone numbers. In the second, nonpublic information was accessible and at least one user’s password was reset.

Within hours of the January breach, we closed the security hole and notified affected account holders. We this blog item about the incident within a few days of first learning about it.

Why are we bringing up these incidents from 18 and 14 months ago that we already told people about? Because the United States Federal Trade Commission (FTC) launched an inquiry into our security practices related to these attacks and today announced that we've reached an agreement that resolves their concerns. Even before the agreement, we'd implemented many of the FTC's suggestions and the agreement formalizes our commitment to those security practices.

Many Twitter users follow their Facebook app, which launched

It's been an eventful week for World Cup fans around the globe. Many have taken to Twitter in record numbers to tweet about coaching decisions, referee calls and, of course, goals.

In this spirit, we thought it would be fun (and instructive) to track the top three most tweeted goals of the tournament so far. These goals had the highest Tweets-per-second (TPS) count in the 30 seconds after a goal was scored.

The most tweeted goals of the past week...

1) deciding game of the NBA Championship between the Los Angeles Lakers and Boston Celtics. The Lakers' victory generated a record 3,085 TPS as the game ended.

For context, Twitter currently sees about 750 TPS on an average day and 65 million total Tweets a day.

The Platform team is always excited to see developers' creativity in building cool applications using our APIs. To showcase new and interesting applications built on the Twitter Platform, we're going to periodically feature great apps on our blog. For our first post, we'd like to highlight the @

The TweetBeat site provides real-time updates from and around the World Cup. You can follow what is being said about the whole tournament, or focus on a specific team and even follow what's happening with its opposition. Not only that, but their Popular Tweets sidebar keeps you informed of what everyone else is talking about and, during matches, which team has the most Tweets.

TweetBeat uses the Twitter Firehose to cluster similar tweets into real-time stories from all across Twitter as they happen. You can use the speed slider to slow down or speed up the flow of Tweets and stories down the page. They have also integrated twitterapi or me (@themattharris) and we'll check it out!

From a site stability and service outage perspective, it's been Twitter's worst month since last October.

If you're like everyone at the Twitter office, you're going crazy about the World Cup. When turning to Twitter to keep up with the current game, it helps to know where a Tweet is coming from—is that person watching the game on TV or is he actually in the stadium? To help answer that question, we're excited to announce Twitter Places on twitter.com and mobile.twitter.com. Starting today, you can tag Tweets with specific places, including all World Cup stadiums in South Africa, and create new Twitter Places. You can also click a Twitter Place within a Tweet to see recent Tweets from a particular location. Try it out during the next match—you will be able to see Tweets coming from the stadium.
Several other features of this launch include: 

• Foursquare and Gowalla integration: Many Foursquare and Gowalla users publish check-ins to Twitter. Location is a key component of these Tweets, so we worked closely with both companies to associate a Twitter Place with Tweets generated by these services. This means that if you click on a Twitter Place, such as "Ritual Roasters," you will see standard Tweets and check-ins from Foursquare and Gowalla.
• API: We are releasing API functionality that lets developers integrate Twitter Places into their applications. 
• Support for more browsers: Now, you can add location to your Tweets from any browser—Safari and Internet Explorer, in addition to Chrome or Firefox. 

The majority of Tweets are sent or read on applications built by the developer community. Likewise, there is a ever-growing number of third-party applications that bring value to users in a variety of new ways. As we Twitter developers website.

The first World Cup took place in 1930 and it has since grown to become an epic global event celebrating diversity and inspiring us to overcome adversity. More importantly, nations and people around the world have the opportunity to connect around something profoundly simple: play! The mission driving suggested accounts to follow during the tournament and a World Cup theme for your profile page. We'll leave it up to you to learn how to do the neat little trick we're calling hashflags.

Every day millions of people use Twitter to create, share and discover information, and as we grow, analytics becomes an increasingly crucial part of improving our service.

Up until about a year ago, we used an online database called Andrew Catton, Luke Andrews to Twitter.

Since can now begin to prepare for this service. They will be able to choose how to display the wrapped links in a manner that is most useful, informative and appropriate for a given device or application. Our first step is a small one. We're rolling out wrapped links on a handful of accounts, including @.CO Internet SAS, the registry for the new .CO extension, for helping us secure t.co for use with this service. Links shared on Twitter will be safer, clearer, and more valuable.
