Alexa Explanation Ortsbo was down on Feb 26th, many people were unable to access the site most likely due to upgrades in the backend servers. https://doublewide1.blogspot.com/2012/02/ortsbo-currently-down.html
However, if you look at the Alexa chart for Feb 26th, it shows that the ranking was stable at the 3 month average of just over 8,000. The Alexa rankings have been pretty accurate to date as we saw many record setting days in the past month which then translated into a record setting 107million unique users. SO, either Ortsbo.com was down again at some point yesterday and nobody noticed here due to all the frantic posting on SH OR the Alexa rankings somehow lag the actual data and yesterdays rank merely reflects the outage on Feb 26th (because the ranking was unaffected on the date we all know the site was down).
I expect that the Ortsbo site will experience outages at times due to the integration of the SYN's Unity platform. A recent Ortsbo2go update on the Iphone stated that the servers were upgraded to dedicated Ortsbo servers:
What's New in Version 1.3
Login and language translation is updated to use new Ortsbo chat server.
-----------
As additional Language and chat platform capabilities become available, service will undoubtedly be interrupted at times and this will reflect in brief downward blips on the Alexa Ranking but will ultimately be a positive sign as it means the entire Ortsbo service is undergoing improvements.
