AlertFox Monitoring Server Update Completed

The most important piece of information first: There is nothing todo for you. This update is completely transparent and does not affect running tests. But should you do encounter anything strange in your account, please notify our tech support immediately and we will investigate it.

Now that you know there is no work for you, sit back and enjoy the list of changes:

Updates:


AlertFox is growing, again

AlertFox is growing and we reserved new IP addresses for monitoring stations in all zones. 

You find the complete list at http://wiki.alertfox.com/IP_Address_Range#Monitoring_Stations

The IP address range information is useful if you want to filter AlertFox access from your web page log files (e. g. in Google Analytics) and/or if you want to give AlertFox access to an otherwise protected website.


Even so we do not utilize all the new IP addresses right now, we highly recommend that you add them to your filter or white list, so you are prepared for future system upgrades.

AlertFox Easter Update - New Control Panel Features

Astronomical spring in the northern hemisphere began on March 20, 2012 - and new AlertFox features start to appear: Today we released the first of many exiting new updates that we have in the works for 2012.


Today's "Easter Update" contains mostly invisible backend changes, but also two important user facing improvements.

Account ID - All accounts can now be easily identified by an Acount ID. You find this account ID directly on your dashboard and also on the account settings page. Please quote it in all communications with us, it will help us to respond faster.

E-Commerce Control Panel - You can now view and print past invoices, see all charges and update your credit card information in one central place. Note: If you do not see this link in your account yet, please contact sales and we can enable this feature for you.

DNS Management Service Zoneedit Down [Update]

The popular DNS management service Zoneedit is experiencing an extended downtime and users are complaining on Twitter. On the positive side, it seems "only" the web interface is affected, and not the DNS services itself. (Update: Site up again after 12 hours of downtime).



We will update this post when Zoneedit is available again. Zoneedit is a great service and we are using it ourself at AlertFox. But we sure wished they had a public dashboard. Every web service should have one.

Webpage Test - Monitor your website's global performance

Today we officially launch our new webpage test tool for website performance monitoring. It allows everyone to run a free website speed test from global multiple locations using real browsers (IE, Firefox and soon Chrome). All you need to do is enter the URL of the site you want to test. AlertFox starts a real browser in the USA, Europe and Asia and reports back the load time of each web page element as resource loading waterfall charts. And you can download the performance report in HAR format for detailed analysis.

If you are already an AlertFox user this test will look familiar to you: It is, of course, nothing other than the iMacros-powered real browser monitoring feature, now available as an online tool for quick and easy website performance tests in between. It is also useful to get global data for comparison with your local iMacros web testing results (e. g. from the iMacros web performance profiler).

Plus, you can share this test easily with your friends and coworkers: Just use the url displayed at the bottom of the page.

Example: Click http://alertfox.com/tools/har/?url=wiki.alertfox.com
to run a performance test for our AlertFox wiki. As result, you will see that the waterfall chart reveals the missing favicon image:




We do our best to keep this tool free for everyone, but testing websites with real browsers is resource intensive. If the use exceeds a certain limit, a captcha will be displayed. As an AlertFox PRO user you can circumvent this by logging into your website monitoring account and starting the test from there.

If you have any performance/optimization questions please ask us. We enjoy discussing Web Performance Optimization questions with you.

Performance Monitoring with Firefox 7

As you know, AlertFox uses real web browsers (as opposed to only simulated ones) for monitoring the real end-user experience and getting realistic website performance data.  


Today we upgraded our global website monitoring stations to Firefox 7 and iMacros V7.4. Internet Explorer remains, of course, at Version 9 (only security updates added). This upgrade is completely transparent. There is nothing to do for you as AlertFox users.

You can always view our current configuration at the backend wiki page.

Website Malware Monitoring with AlertFox

Website Malware Monitoring at AlertFox
Did you know AlertFox can also monitor your site for malware?   Malware distribution (viruses, Trojans, spyware etc.) has become a key issue for many website owners, as drive-by-download attacks are on the rise and malware distribution techniques are becoming increasingly effective.

There are expensive malware monitoring services like GlobalSign or HackAlert  - but the AlertFox real browser monitoring service provides you a similar security for free.

How do we do this? We use real web browsers for testing your site, and the malware monitoring comes as side effect, courtesy of Google.

This is how it works: 

Lets assume your site just got hacked...

1. Googlebot crawls your site every x minutes (x depends on how popular your site is)

2. As soon as Googlebot detects malware, that info is sent to the safe browsing list of Google, which is used by Chrome and Firefox.

3. On our test stations, the running browsers retrieve the latest malware update - and boing! - your transaction test will fail because the browsers block your site - and you get alerted by AlertFox!

To summarize, by using AlertFox Website Monitoring you get the power of Google's phishing and malware monitoring at no additional costs!

For more information on malware, see the Google Malware and Hacked Sites forum.

How to setup malware monitoring? If you already have a Firefox based transaction test running there is nothing else to do! Malware monitoring is active by default!

1and1 down - or why you need external website monitoring

Update 3: 1and1 up again. See our 1and1 network status page for details.

Update 2:  Down again! You can follow the up- and down on our public 1and1 network status page (based on the uptime monitoring wiki that we host at 1and1).
 
Update : 1and1 servers are up again (after more than 1.5h of downtime):

1and1 downtime as logged by AlertFox. The time zone is GMT (London).

Unfortunately our AlertFox wiki is currently a case study on why you need an external website monitoring service. One of our hosting providers, 1and1 (spelled "1und1" in German) is currently having a major network downtime. All 1and1 dedicated servers include an internal (1and1 hosted) monitoring service - which still showed all green while Twitter was already flooded with complaints. So the only thing this internal server monitoring service is good for is to show us that somewhere, deep inside the 1and1 datacenter our server is still up and running.


AlertFox detected the problem. You can follow our Wiki page status on our public status dashboard (Wiki page status at: http://status.alertfox.com/47514).

Note that this downtime "only" affects wiki and support center. Our core monitoring and user control center is not affected at all.
