Companies servicing the largest
numbers of SSL sites, August 2003
Company SSL Sites
uu.net 6,950
verio.net 4,243
ATT 4,019
Interland 3,946
Cable and Wireless 3,038
Qwest 2,908
Sprint 2,787

Self hosting is still a popular option for SSL site owners whose sites perform encrypted transactions and ecommerce. When counted by reverse DNS, the largest aggregations of SSL sites are on networks at companies whose main business is selling connectivity rather than hosting.

Of the top seven providers, only Interland is exclusively a hosting provider, although Verio is best known for hosting and all of the others have significant hosting operations. Interland's early focus on the mid-market and the Windows platform, which is favoured by many internet retail sites, has helped create its position as the leading hosting location for encrypted transactions.

Rackspace's site was down for around two and a half hours early this morning [BST], in what may likely have been a repeat of Tuesday's distributed denial of service attack.

The response times to our own performance collector on Rackspace's network indicate that the attack did not adversely affect response times to other machines at Rackspace.

Although PHP is universally thought of as implying Linux, Apache and MySQL, nearly 7% of PHP sites [when counting by ip address] run on Windows. This has doubled over the last year, and on its current growth trajectory PHP will overtake Cold Fusion as the most popular non-Microsoft scripting language used on Windows during the next year.

On Friday evening [BST] US authorities charged Jeffery Parsons with creating a variant of the Blaster worm know as “Blaster B”. Such a trail of clues pointed to Parsons that those investigating the case must have initially expected that they were dealing with a case of identity theft, but from the reports it seems that Parsons had modified and re-released the worm “because he could” giving no thought to the potential consequences for himself.

The recent spate of distributed denial of service attacks has diversified, with some attackers apparently now targetting hosting companies.

failed requests at www.rackshack.net

On Tuesday rackspace.com was attacked just one day after issuing a press release launching a service to mitigate the effects of DDoS attacks, while early this morning[BST] Rackshack appeared to suffer a similar attack.

Rackshack have posted to their support forums that their power consumption has hit the limit of the local Houston power grid.

Rackshack expects to have a second datacenter, also in Houston, but on a different segment of the power grid, in the first few days of September, and that [at the time of the posting] it had around 600 servers available to rent in its existing datacenter. 600 servers sounds a lot and more than the entire installed base of many hosting companies, but Rackshack is one of the market leaders in Linux/Apache dedicated servers and has been adding in the region of 1000 new Linux servers per month to its network.

Our site was inaccessible for about 9 hours yesterday between 5pm and 1:30am BST [9am - 5:30pm Pacific]. We are informed that this was caused by a serious fibre break on the Energis network. Apologies.

Netcraft has developed a service whereby hosting service providers can have access to detailed information on the present performance of their prospects’ sites, including timely notification of outages and the facility to compare and rank performance of the monitored sites.

The SCO site has been up during business hours in Utah, but has since failed again. Many news sites carried the story that Eric Raymond had spoken to agroup responsible for a Distributed Denial of Service attack on the www.sco.com site and that they agreed to stop. However it appears that this may have been a hoax, or they subsequently changed their minds, or another person decided to continue the attack, or that the timeout on the attack has not yet been reached.

In a similar situation 10 days ago Microsoft chose to deploy Akamai's caching service, which has successfully averted any outages.

Akamai would be more dependable at warding off Distributed Denial of Service attacks than favours from Eric Raymond, but concievably SCO may have difficulty swallowing its pride and buying a service that uses tens of thousands of Linux servers, for which Akamai presumably has not purchased a SCO licence.

Nick Marsh points out that the www.sco.com site has been down for a long time - now over two days so far according to our performance measurements.

At the moment, it is not known whether the SCO site has been successfully attacked, intentionally taken down, has lost connectivity or has simply broken.

Linux distribution share likely to change

One company that has a firm grip on its customers' attention is Red Hat, which has made significant changes to the licencing, pricing and support of its Linux distribution. Red Hat is presently the most widely deployed Linux distribution on the websites we find on the internet. However, it is clearly prepared to lose significant market share in an effort to increase revenue.

Companies with the largest current exposure to Red Hat, August 2003

rackshack.net 11,987 131,326 205,239
Rackspace 6,931 57,852 141,506

www.microsoft.com runs Linux? Up to a point ...

On Friday Microsoft changed its DNS so that requests for www.microsoft.com no longer resolve to machines on Microsoft’s own network, but instead are handled by the Akamai caching system, which runs Linux.

Debian Linux distribution 10 years old today

Following on from the FreeBSD project which celebrated its 10th anniversary a few months ago, the Debian Linux distribution reached the age of 10 today. Debian has been an amateur effort throughout its lifetime, and its success is a testament to how little difference money sometimes makes.

Despite the abscence of funding, Debian is the second most popular Linux distribution we find on internet web sites, surpassed only by Red Hat, and leaving the likes of SuSE and Mandrake in its wake. Arguably, Debian is the most cosmopolitan of any of the Linux distributions, having a significant following in the former Iron Curtain countries, and well represented in almost every country.

Geographical Distribution of sites running on Debian Linux

Leading sites running Debian include TheRegister and T-Mobile.

Outage at microsoft.com not likely to be part of general attack on Internet infrastructure

Overnight, microsoft.com has suffered an outage of a little over an hour. Microsoft have posted to the effect that this was caused by a [presumably non-http] denial of service that is not associated with any known vulnerability in Microsoft's own software. Speculation on Information Week that the outage might be part of a broader attack on internet infrastructure or linked to the start of the Defcon conference seems implausible, as only one other Fortune 100 site has shown an outage in the last 24 hours. Three of the 52 leading hosting providers monitored by Netcraft are showing outages in the last 24 hours, but all three are outside the US.

August 2003 Web Server Survey

The Netcraft Webserver Survey is 8 years old this month. Happy Birthday!

The first Web Server Survey ran in August 1995 and found 18,957 sites. NCSA and CERN were the leading web servers of the day, in front of Netscape which had recently IPO'd, and the Apache project which started a few months earlier in March 1995. Microsoft-IIS, HTTP/1.1 hosting and domain name registrars were not then on the horizon.

In the August 2003 survey we received responses from 42,807,275 sites.

Apache hits an all time high in percentage share this month with 63.98% of sites found running an Apache server.

Following on from last month, Microsoft continued to lose sites as Network Solutions migrated the rest of their domain parking system back to Solaris from a Windows based system hosted at Interland. This is primarily responsible for Microsoft's 2.2% fall, with a net loss of 810,597 sites.
