Sweden node has been online all weekend, and still is. Same with russian (1 & 2). Contact form is this form. A ticket system is being written but as of yet this is the quickest method of contact (as we are still a wJunction based service).
We have 3rd party uptime monitoring monitoring all 3 nodes, nothing was reported either.
@Kamil: Bad Gateway signifies an error connecting to your server and is not an issue with our end. Most likely, overloaded server or firewall blocking connections on your server. If you contact me while it is happening I can tell you what is going on.
Im working on a connection debug tool at the moment to be included in the site.

On an unrelated not, the much requested feature of low balence alerts has been added, you should receive alerts. You will receive notifications at $10, $5 and $0. I will work on a better system that takes into consideration plan cost and number of IPs in the future, so sorry if these intervals are not applicable for you. Emails are sent to the email address you registered with.
Since some people are making statements about uptime I have signed up to a new monitoring service which provides public statistical access.
