Infoworld.com experiences a "massive surge of RSS newsreader activity at the top of every hour," according to Chad Dickerson, the CTO of Infoworld. "If I didn’t know how RSS worked, I would think we were being slammed by a bunch of zombies sitting on compromised home PCs," Dickerson writes. "Our hourly RSS surge has all the characteristics of a distributed DoS attack, and although the requests are legitimate and small, the sheer number of requests in that short time period creates some aggravating scaling issues."Continue reading
Online betting sites have been repeatedly targeted by extortionists employing electronic attacks, including a series of distributed denial of service (DDoS) attacks at the outset of the Euro 2004 event.
Netcraft is monitoring the performance of twenty leading UK Internet Gambling Sites, with dynamically updating graphs available here.
June 1st - 30th 2004
During June all of the hosters monitored experienced an outage. Seeweb, an Italian hosting company, was once again the most reliable hoster, taking first place two months in a row. Second placed was the Pair Networks site.

The RIAA site began experiencing performance problems again this morning, although it seems to be faring somewhat better than on previous MyDoom.F trigger dates. The site index is using a text-only redirection page at www.riaa.com in an attempt to reduce the load on its server.
A dynamically updating graph of the sites targeted for DDoS by various MyDoom variants is available here.Continue reading
The performance problems affected Microsoft, Google, Yahoo and antivirus update services from Symantec and TrendMicro, which are among Akamai's 1,100 customers. Some of the largest affected sites were able to switch their DNS settings to their internal network, rather than akadns.net, which handles domain name service management for Akamai customers. The akadns.net system routs requests for high-volume customer web pages to content stored on its network of distributed servers, easing traffic to the client's main server and speeding delivery to the end user. Akamai performs similar function for downloads of audio and video files, software patches and antivirus definitions.
The outages mark the second disruption of Akamai's network in less than a month, following a similar incident May 24.
