Nov 12: Intermittent problems between 3:35 pm and 5:35 pm (EST)

(Updated:)

At 3:35 pm our monitoring systems alerted us that some client websites are responding slowly or even returning "Server is busy" message. Our technical team has immediately jumped on the problem. We could not find the problem right away so initiated a reboot of our servers. After the restart most client sites started to work but quite a few were still very slow and were occasionally throwing "Server is busy"message.
Our further investigation indicated that the most likely reason is excessive traffic (possibly a DDOS - Distributed denial of service attack) to one of the sites on our platform. Once we were able to identify the site in question, we have disabled it and this has restored normal functioning to all clients.

The bottom line is that between 3:35 pm EST and 5:35 pm EST some users accessing some client websites experienced very slow replies or even occasional Server is busy messages. (As we have a webfarm with multiple servers, the same site worked fine for some visitors and malfunctioned for others accessing it from somewhere else or a few seconds apart).

As of 5:35 pm all sites are functioning normally.

We will be continuing our investigation to the root cause of this problem and working to prevent re-occurrences of this.

We sincerely apologize for the inconvenience.
