PayPal.com unexpectedly offline

PayPal.com experienced some unexpected outages today, leaving many of its 165 million active customers unable to access the site via its paypal.com domain.

p-3894.652

All of Netcraft's geographically distributed performance monitors have showed outages of at least an hour so far today.

But requests to www.paypal.com continued to work throughout the outage, and customers could successfully log in by browsing directly to that hostname; however, it is likely that many users visit the site by typing only "paypal.com" into their browser's address bar.

The shorter paypal.com address does not serve a homepage; its sole purpose is to redirect visitors directly to the main www.paypal.com website. This shortcut saves the user having to type "www." into his browser, but during the outage, anyone attempting to reach the site via this commonly used method would have faced error messages similar to this (unless the redirect has been cached from a previous visit):

timeout

Even a short outage can have a huge impact on a financial giant like PayPal. In 2014, PayPal handled 4 billion payments with a total payment volume of $235 billion.

The cause of the outage is as yet unknown: The PayPal Notifications website does not show any scheduled maintenance for the live site until tomorrow, and does not currently list any unscheduled events corresponding to today's outage.

EveryCity had the most reliable website during May 2015, responding to all but two of Netcraft's requests. Since Netcraft began monitoring its site in April 2014, EveryCity has maintained a 100% uptime record. Besides SmartOS-based hosting, EveryCity also specialises in Solaris hosting on both SPARC and Intel platforms.

In second place is Datapipe, with just four failed requests to its website during May 2015. Two other companies had the same number of failures: Anexia and CWCS. Datapipe's impressively quick average connection time (0.012 seconds) gives it the edge in the tie-breaker, fending off both Anexia (0.088 seconds) and CWCS (0.104 seconds). Datapipe has data centres in key technology and financial hubs including New York, Silicon Valley, London, and Hong Kong.

Anexia (3rd place) and CWCS (4th place), both with four failed requests and both of which are based in Europe, differ in their focus: Anexia operates 58 data centres across the world, whereas CWCS concentrates on the UK market, owning two "state of the art" British data centres. Anexia announced in early May that it had become an official Debian mirror, providing support to the open-source project.

Making it into the top 10 for the first time since its monitoring began in February 2015, Umbee Hosting's website responded to all but a handful of Netcraft's requests. Umbee Hosting has five data centres, spread across three continents: two in the London region, two in metro New York, and one in Sydney.

Linux remains a popular choice amongst the top 10 hosting company websites, powering six. The use of SmartOS and FreeBSD brings up the total of UNIX-based operating systems to eight. The remaining two are powered by Windows Server 2008 and 2012.

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.

Information on the measurement process and current measurements is available.

Datapipe had the most reliable hosting company website in April, responding successfully to all of Netcraft's requests; Datapipe has now featured in the top ten for eight consecutive months, and has maintained 100% uptime over the last nine years. In April, Datapipe announced that it had become one of the first AWS Managed Service Provider Partners, certifying that Datapipe "[offers] proactive monitoring, automation, and management of their customer's AWS environment".

With just a single failed request, GoDaddy came in second place. GoDaddy, the world's largest registrar, recently listed on the New York Stock Exchange, bought the GDDY.com domain name to match its stock ticker symbol, and will announce its first quarter 2015 results on 12th May.

ServerStack came in third place in April, narrowly missing second place with just a single failed request separating it from GoDaddy. ServerStack provides managed hosting services to enterprises, targeting companies spending more than $10,000 per month on hosting. Its data centres are based in San Jose, New Jersey and Amsterdam.

Once again, Linux was the most popular operating system for hosting company sites, powering 7 of the top 10 websites. Windows Server 2012, SmartOS and Citrix Netscaler all appear once each.

Bigstep had the most reliable hosting company website in March, responding to all of our requests. This is the 13th time that Bigstep has appeared in the top 10 since Netcraft began monitoring its website in March 2013, and the first time it has topped the ranking. Bigstep offers "full metal" cloud services from data centres in the UK and Germany, providing bare metal hosting with the flexibility of the cloud.

Netcetera's website also responded to all of our requests in March, placing second due to a slightly slower average connect time. Netcetera run a carbon neutral data centre on the Isle of Man and offers shared, dedicated and cloud hosting services.

Four websites responded to all but one request in March, Datapipe, Qube Managed Services, EveryCity and Codero. Datapipe is ranked in third place based on its shorter average connect time, having taken one of the top three spots in four of the past five months. Datapipe boasts a 100% Network Uptime Guarantee, and has kept this promise on its own site, with 100% uptime for the past 9 years.

Linux remains the most popular operating system in the top 10 with six of the hosting companies choosing to use the OS for their websites. The four other websites all use different operating systems: Windows Server 2012, SmartOS, Citrix Netscaler and FreeBSD.

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.

Datapipe had the most reliable hosting company site in February, with just two failed requests. Datapipe recently acquired cloud hosting company GoGrid, claiming that GoGrid's technology will allow its customers to quickly and easily deploy big data services, such as NoSQL databases. The acquisition also gives Datapipe three new data centres located in Amsterdam, North Virginia and San Francisco, bringing the total number of data centre locations to ten.

EveryCity followed closely in second place, with the same number of failed requests as Datapipe but with a slightly longer average connection time. EveryCity's managed hosting customers receive its "elite" service as standard, which guarantees 100% uptime and round the clock support. Netcraft has not observed any outages of EveryCity's site since monitoring began in April 2014, and it has previously been featured in the top ten on six occasions.

In third place, Qube Managed Services had four failed requests. Qube offers a managed private cloud hosting service that provides a secure virtual hosting environment dedicated to individual businesses. This provides the ability to quickly scale capacity up and down according to demand, whilst also ensuring that data is physically segregated between different organisations.

Linux remains the most popular choice of operating system, with seven of the top ten hosting company sites using the OS this month. Netcetera's and Aruba's sites are both served from Windows Server 2012 machines. EveryCity uses SmartOS, an open-source operating system based on OpenSolaris.

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.

Amazon goes down in Europe

Some of Amazon's European retail sites and video streaming services went down last night, causing a flurry of complaints across social media. The affected sites included amazon.co.uk, amazon.de and amazon.fr.

p-3915.170

These outages are particularly notable, as Amazon has a considerable amount of experience hosting websites. It has one of the largest hosting infrastructures in the world, which is used not only by itself, but also by thousands of its Amazon Web Services customers.

Amazon is the world's largest hosting provider in terms of web-facing computers, accounting for more than 6% of the 5.1 million computers in Netcraft's February 2015 Web Server Survey. 52,000 of Amazon's web-facing computers are located in Ireland, which is where its European retail sites are hosted.

Amazon's presence in Ireland has grown astonishingly since Amazon Data Services Ireland opened the first of its three Irish EC2 Availability Zones in 2007. Remarkably, more than three-quarters of all web-facing computers in Ireland are now operated by Amazon, and these account for 2.7% of all web-facing computers in the Europe, Middle East and Africa region which it is designed to serve.

Amazon's US site at www.amazon.com, which is hosted in the US, was not affected by last night's outages.
