Renesys earlier confirmed that Egyptian internet providers had returned to the internet just before 09:30 UTC; however, a few important sites mysteriously went back offline a short while later.
www.mcit.gov.eg came online for a brief period, but then went offline again less than an hour later:
Before Egypt shut down internet access, the online collective Anonymous had been carrying out a distributed denial of service attack against this site; however, that attack did not appear to succeed at the time.
Meanwhile, www.egypt.gov.eg has been online solidly since Egypt returned to the internet, whereas www.moiegypt.gov.eg has been coming and going:
This site was also attacked as part of an online protest by Anonymous, which resulted in some short outages on 26th January.
A tweet from AnonymousIRC suggests that this site may be being kept offline by a second DDoS attack:
We are continuing to monitor the performance of several Egyptian sites at http://uptime.netcraft.com/perf/reports/performance/wikileaks
The popular is.gd URL shortening service was reportedly unavailable for a few hours this morning, effectively breaking thousands of shortlinks posted to Twitter and other social networking sites. During the outage, the site's public-facing load balancer responded to PING requests, but was refusing HTTP connections to port 80.
is.gd is one of the most popular URL shortening services in current use – it has shortened 334 million URLs to date, which have been accessed more than 11 billion times. The service is wholly owned by UK hosting company Memset, which hosts the site on their own servers. Since December, Memset has also provided a shorter v.gd service, but this has only attracted 61 thousand URLs so far.
Memset told Netcraft that today's fault was caused by the failure of some virtual machines in the frontend cloud, which is responsible for accepting HTTP requests from the load balancer. These have been restored and the site is now back up and running with improved monitoring processes.
is.gd is primarily maintained by its creator, Richard West, a freelance developer and technologist. Memset proudly describe it as an "ethical" URL shortener; in particular, they have pledged to support is.gd as a free service indefinitely, will never place third-party adverts on the site and claim to be one of the most proactive URL shorteners in preventing spam and misuse.
Other sites hosted by Memset, including its own main presence at
memset.com, were unaffected during the is.gd outage.
A new local crime and policing website for England and Wales was launched late last night at police.uk. The revamped site provides instant access to street-level crime maps and data – or at least, it did until curious members of the public woke up this morning.
In what could arguably be described as a media-driven DDoS, the new site has received a lot of publicity
on the internet, radio and television today. As a result, a huge number of visitors appears to have swamped the police.uk site with traffic, causing it to break. Search results are currently returning error messages, or a blank page with a 503 Service Unavailable response header.
One response worryingly suggests there are no police in London:
The new police.uk site has been developed by advertising agency Rock Kitchen Harris, who also developed the original CrimeMapper site for all 43 English and Welsh police forces in 2009. The launch was announced today on their website, where they said:
"We not only designed, built and manage the site we also arranged the hosting using a mix of servers, with the public website using scaleable cloud hosting."
Despite the use of scaleable cloud hosting (in this case, Amazon EC2), the site does not appear to be holding out too well. Amazon's EC2 hosting service does provide a facility called Auto Scaling, which deals with traffic spikes by automatically increasing capacity, but it is not clear whether RKH have enabled this feature. WikiLeaks notably used Amazon EC2 when the Iraq War Logs and Cablegate sites went live, both of which coped well with the initial large volume of traffic.
Netcraft was unable to speak to anyone in the web team at RKH, as they are, understandably, "a bit tied up at the moment", but it was confirmed that the current problem is a result of too much traffic.
Following the recent uprising in Tunisia, thousands of demonstrators took to the streets in Egypt yesterday to demand an end to President Hosni Mubarak's rule. The online collective known as Anonymous has joined in the protests by orchestrating distributed denial of service attacks against key Egyptian websites.
Operation: Egypt began its recruitment campaign 3 days ago, inviting participants to join the #OpEgypt channel on its IRC network. As with the previous attacks against PayPal, MasterCard and Visa, volunteers are being sought to install and run the Low Orbit Ion Cannon (LOIC) software, which can automatically bombard a website with a large volume of traffic.
Last night, Twitter confirmed that it had been blocked in Egypt:
Some of the earlier DDoS attacks carried out by Anonymous had used Twitter feeds to announce targets to the automated attack software. IRC appears to be the primary control point now, with the current target set to
www.mcit.gov.eg – The Egyptian Ministry of Communications and Information Technology.
It is not clear how many people are involved in this attack, but our performance data for www.mcit.gov.eg shows the website is currently up and responding to HTTP requests from around the world.
This could suggest that the number of volunteers taking part in the attacks has continued to decrease over the past few months. In an interview earlier this month, Anonymous member Sven Slootweg said that he did not expect many more DDoS attacks as the impact is limited.
To muster up more attackers, the IRC channel also invites users to use a web-based version of the LOIC attack tool, which can even be used from mobile phones.
Further discussions, including which targets to attack, are being carried out on the interactive multi-user PiratePad site:
This also lists www.moiegypt.gov.eg as a main target, which has experienced some short outages (performance graphs).
Popular BitTorrent site The Pirate Bay is one of many joining in with today's "blackout" protests against a new media law approved in Hungary. The law allows Hungarian publications to be fined for violating public order, which could require journalists to reveal their sources.
The blackout campaign is being publicised through blackout4hungary.net, which encourages other sites to take part in the protest by adding black banners or stylesheets to their sites. The blackout4hungary.net site appears to have taken the blackout concept a step further and is currently offline, although this may just be a consequence of the large amount of traffic being driven to the site through hyperlinks and hotlinked stylesheets.
The Pirate Bay is currently hosted in Germany and uses the lighttpd web server. The site has nearly 5 million registered users and claims to be "the world's most resilient BitTorrent"; however, the site's availability has been somewhat choppy since Tuesday.
4chan's popular message boards are under another distributed denial of service attack. Many members of Anonymous inhabit the site's boards, although it is unknown whether the current attack is related to any of the previous DDoS attacks purportedly carried out by Anonymous.
Shortly after the attack began, an update on status.4chan.org quickly stated, "Another day, another DDoS! Right on the eve of /b/'s 300 millionth post."
4Chan was also subjected to a similar attack last week, whereupon it quipped, "We now join the ranks of MasterCard, Visa, PayPal, et al.–an exclusive club!" These payment companies had previously been targeted by Anonymous in a series of attacks last month.
