The social networking site Facebook suffered a period of short outages yesterday.
A spokesman told the BBC that the outage was not thought to have affected every country, but Netcraft found the site to be unavailable from all of its performance collectors, located in London, Pennsylvania, San Jose, Phoenix, New York, Virginia and Italy.
Facebook's popularity has continued to grow and is now the 33rd most visited site by users of the Netcraft toolbar. Originally called "The Facebook", the company renamed itself after purchasing the domain facebook.com in 2005 for $200,000. By October 2007, Microsoft announced that it had bought a 1.6% share in Facebook for $246 million.
An outage affected the Mozilla.com website on the day the organisation launched its Guinness World Record attempt for downloads of the new Firefox 3 browser.
The mozilla.com site was unreachable from around the world, occasionally responding with the message, "Http/1.1 Service Unavailable".
Melissa Shapiro posted a statement on the Mozilla blog to say that their servers were feeling the burn and should be back to normal shortly.
An earlier post stated that the record attempt would begin today at 5pm UTC, but Shapiro announced after this time that the 24 hour period in which the downloads will be counted will begin once the site goes live.
Netcraft was able to access the Firefox 3 download page again shortly after 7pm UTC, but the Service Unavailable message was still seen occasionally. For some period before this, the page was still offering version 2 downloads, yet a Mozilla press release confirmed that Firefox 3 had indeed already been released.
A follow-up post on the Mozilla blog officially announced that the 24 hour period had begun, with Guinness counting all complete downloads of Firefox 3 before 18:16 UTC tomorrow.
The outages also affected the www.spreadfirefox.com website. Realtime performance graphs of the Mozilla website are available here.

Static uptime graph for www.slashdot.org
Netcraft's live monitoring of www.slashdot.org can be seen here,
reflecting a contiguous outage of approximately 5 hours.
The CNN News website has twice been affected since an earlier distributed denial of service attack last Thursday. CNN fixed Thursday's attack by limiting the number of users who could access the site from specific geographical areas.
Subsequently, an attack was purportedly organised to start on Saturday 19th April, but cancelled.
However, our performance monitoring graph shows CNN's website suffered downtime within a 3 hour period on Sunday morning, followed by other anomalous activity on Monday morning, where response times were greatly inflated.
Netcraft is continuing to monitor the CNN News website. Live uptime graphs can be viewed here.
