Both of the top two hosting companies had the same number of failed requests this month and they are therefore ranked by average connection time.

Top of the table this month is Hosting 4 Less. The company guarantees 99.9% uptime, with its own OC48 Sonet Ring connecting their secure data center to the internet. Hosting 4 Less has been running since 1998. They offer both Linux and Windows hosting as well as e-commerce hosting.

The second most reliable hosting company for July was PoundHost who are based in the UK and offer a range of hosting solutions, including dedicated servers, co-location and virtual hosting.

Third this month was Datapipe, which offers a range of services including managed hosting, compliance, security and cloud computing. Datapipe offers a 100% network uptime guarantee.

Seven sites in the top 10 this month were running Linux, two were running FreeBSD and one was running Windows Server 2008.

Netcraft measures and makes available the response times of around forty leading hosting providers' sites. The performance measurements are made at fifteen minute intervals from separate points around the internet, and averages are calculated over the immediately preceding 24 hour period.

From a customer's point of view, the percentage of failed requests is more pertinent than outages on hosting companies' own sites, as this gives a pointer to reliability of routing, and this is why we choose to rank our table by fewest failed requests, rather than shortest periods of outage. In the event the number of failed requests are equal then sites are ranked by average connection times.

Leader.ir under attack?

The website of the Supreme Leader of Iran, Sayyid Ali Khamenei, has been responding very slowly or not at all for most of the day, which is often symptomatic of a distributed denial of service (DDoS) attack. However, with nobody claiming responsibility for such an attack – which is rather unusual lately – there could well be a less nefarious reason for the problems.

Earlier this year, the 'hacktivist' group Anonymous orchestrated a DDoS attack against leader.ir in support of Operation Iran, which accused Iran of operating an illegal regime for the past 32 years. This attack was not successful, but a separate attack against the Islamic Republic of Iran Broadcaster (irib.ir) did appear to succeed.

Datapipe was the most reliable hosting company in May 2011 with only a single failed request from Netcraft's performance monitors this month. Datapipe provides a range of managed services and colocation from data centres in New Jersey, California, London, Shanghai and Hong Kong. In May, Datapipe announced it had secured $176 million dollars in equity and finance to accelerate its expansion.

The second most reliable hosting company in May was www.serverbeach.com, which failed to respond to only two requests. ServerBeach offer cloud services, dedicated servers, managed hosting and colocation. As a child company of PEER 1 hosting, ServerBeach uses its parent company's IT infrastructure and network backbone.

Blogger maintenance causes extended outage

Blogger is currently experiencing an extended outage after Wednesday's scheduled maintenance introduced some problems. The site was taken down again at approximately 20:00 UTC on Thursday and is still unavailable to blog authors.

Blogger is running in read-only mode while the problem is resolved. This means blogs can still be visited, but authors cannot write new posts and visitors cannot submit comments.

The Blogger Status blog, which is itself hosted on the Blogger platform, has not been updated since Monday. The most recent post read, "Blogger will go into read-only mode Wednesday (5/11) 10:00PM PST for about an hour for maintenance".

There has been speculation that the current outage was caused by a new user interface being rolled out; however, Blogger confirmed through its Twitter stream that this was not the cause.

Some users have expressed anger at losing posts and comments. A Google employee confirmed that Blogger had rolled back to a previous maintenance release, causing all posts and comments made after 7:37 am PDT on May 11 to be removed. The most recent tweet from Blogger suggests that these have only been temporarily removed.

Heading the table for April with only two failed requests from any of the performance monitors during the month was Rackspace. Rackspace provides managed and cloud hosting from nine datacentres in the U.S., the U.K. and China. Rackspace frequently features in Netcraft's top ten most reliable hosting companies, having appeared five times in the last year.

Second most reliable this month was Qube, a London-based hosting company which also has datacentres in New York and Zurich. Qube provide managed hosting, managed colocation and cloud hosting for a wide variety of customers, particularly in the areas of finance and new media. Although Qube has previously appeared in the top ten, this is the first time the hosting company has made it to the top three.

The third most reliable hosting company in April was Netcetera. Netcetera experienced the same number of failed requests as Qube, but had a longer average connection time. Netcetera provides a wide range of colocation, hosting and cloud services to customers throughout the world.

Five of the top ten sites this month were running on Linux, two were running on FreeBSD, and one on Windows. Rackspace's site, which performed best this month, is hosted on F5 Big-IP.

Netcraft measures and makes available the response times of around forty leading hosting providers' sites. The performance measurements are made at fifteen minute intervals from separate points around the internet, and averages are calculated over the immediately preceding 24 hour period.
