Obama is DOWN!

Tuesday, March 24th, 2009

I just got an alert via twitter, sent from ServerMojo telling me the presidents web site is missing!

Here’s todays chart showing the angry red downtime clearly..

Obama.com Downtime

The downtime lasted from 17:35 to 18:25 (GMT) so for 50 minutes, obama.com was MIA.

As it is now back online, the world can breathe a sigh of relief but had those folks at the whitehouse been using ServerMojo, perhaps they’d have fixed it sooner.. ;)

You can follow the status of obama.com here..

Twitter aflutter..

Friday, March 20th, 2009

Seems like Twitter is having a bad day with multiple slowdowns and timeouts over the last 24 hours as can be seen on the following charts.. (all times are GMT)

Twitter Uptime (last 24 hours):

Twitter Response Time (last 24 hours):

As you can see the down periods correspond with spikes in response times meaning the page fetch timed out when we checked it – we have a default 5 second timeout for http tests and when a page (html only) takes over 5 secs to download its not generally a good thing. As a result and at the time of writing this blog post their uptime for the last hour is down to 89.86% and 97.19% for the day which for a system as popular as Twitter is sure to annoy many. In fact a quick search shows many complaining tweets already and it’s only a matter of time before they get raked over the coals again by Techcrunch! ;)

Compare that with the last month and you will see that its usually much better even though they do still have the occasional dip in performance..

Twitter Uptime (last month):

Twitter Response Time (last month):

In fact twitter uptime over the last month has been a fairly respectable 99.76% and for the year so far it is 99.85% so not too shabby overall and the infamous fail whale has not had as many opportunities to show itself recently as it did last year!

Just a reminder – not only do we monitor sites but we also provide alerts direct to your twitter account! You can follow us here: http://twitter.com/servermojo to keep up with the latest ServerMojo happenings in 140 characters.

** UPDATE: its been a couple of hours since I first posted this and there is clearly an ongoing performance issue at twitter today – the last few hours have been significantly slower than usual and in fact the average response time for today has reached 1211ms. Compare that to the time for the year so far which is only 633ms, for the last month 850ms and last week 898ms, so its quite a change and in fact appears to be trending towards increased slowness in general. So what is going on at Twitter HQ today? Is it the increased visibility of the search link resulting in their servers getting hammered? Or is there some event going on now causing a big increase in tweets?

New Test Node – Madrid/Spain

Thursday, March 19th, 2009

We have just added a new test node to our test array, this one located in Madrid, Spain.

It is also our first sponsored node, sponsored and hosted by cyberneticos.com, which offers both dedicated and VPS hosting. 
Be sure to check out cyberneticos.com for more information about their hosting plans and hosting facility in Spain.

Already fully operational, the testing node at cyberneticos.com, which is a VPS node with 512MB-1GB memory, and a decent CPU share is easily operating at an extremely low load and CPU usage, which is a very good indication of the server’s status. Naturally we keep monitoring our own testing nodes. :)

cyberneticos.com is also a ServerMojo user and came up with some nice feedback about sub-accounts and other UI aspects that were implemented. Thanks for the feedback and the server, Anthony.

We would like to take this opportunity to say that we are constantly looking for more testing nodes, in new/different geographical locations. If any other hosts are interested in sponsoring test nodes, please contact our support team (see support for details).

Public Stats Pages

Monday, March 9th, 2009

Existing users may have noticed that on the settings page there is an option for public or private stats. What you may not have known (since we didn’t post it anywhere) was what your public stats urls actually are – until now.

Now you will see the public stats url displayed on all the relevant pages so you can share this url or post it anywhere to show other people your server uptime stats. Thanks to CogDogBlog for reminding us! :)

If you have any questions or suggestions, give us a shout.

Traceroutes and server errors..

Thursday, March 5th, 2009

Now available on all accounts is additional info about why a monitor shows downtime – for example was it a timeout, a 404 or 500 error etc. This info is collected when we scan your server and then included in alerts we send you but now is also available on the site – on monitor view pages and on the overview page you will see a little info icon Info next to any downtimes listed there. You can mouseover this icon to see the error message and click it to see further info if available. Also on the monitor list page any time a monitor is down and shows the red error icon Offline you can also mouseover and click that icon for the error details.

Also now available for “big biz” type accounts are traceroutes which can be performed any time a server is found to be down – to enable this feature just check the “TraceRoute Snapshot?” box on the monitor create or edit form (only available on certain types of monitors such as ping). Traceroutes can then be viewed, as the following image shows, by clicking on the info icons as described above.

Traceroute Example

We hope all this additional monitoring data will help you diagnose server or network problems and ultimately enable you provide a more reliable service to your own users.

If you have any questions or suggestions – please let us know! :)

Handy Icons

Wednesday, March 4th, 2009

Another day another nifty feature added to ServerMojo!

Today we added dynamic status icons to go along with the page refresh. What this means is that a small icon appears next to the url in your browser and also in the tab (assuming you use a browser with tabs) where servermojo is open. So, when your server or monitor is online it will show a green icon online in the tab and when it goes offline it will change to a red icon offline so you can see at a glance when any of your monitors change status while you are online without having to actually go to the servermojo page! Handy Harry!

The status icons show on individual monitor pages, the overview page and the monitor list page and the refresh interval depends on the scan interval you define for your monitors.

More niftyness to follow! :)

New Sub-Accounts Feature

Tuesday, March 3rd, 2009

We just released a new sub-accounts feature (for premium accounts) which you will see when you login to your account.

Sub-accounts allow you to create read-only (for now) accounts for others such as employees or clients to use. They can login and view stats for monitors associated with that sub-account. Alerts can be sent to contacts from multiple sub-accounts so you can give multiple users access to alerts and stats for any monitor. In future we plan to add even more abilities to these sub-accounts.

As always we welcome feedback so let us know what you think about this new feature or any others in the new ServerMojo.
