Perhaps somebody remembers situation with MightyExtension website when it was down very often. So, today they have opinion that site is not stable still. But I should dispel it.
If you see that Uptime Statictic of MightyExtensions you can see that downtime periods less than 99%.
Also, yesterday (12 June 2011) downtime issue was due hosting company. And it was lasting 1 hour 25 minutes just. So if you feel problem with opening MightyExtensions site, please, be sure that site is realy offline by link http://stats.pingdom.com/it3nmvbfyz0y/290701
