SORRY FOR THE EXTREME DOWNTIME! Apparently our server was targeted by hackers and was being attacked via brute force/Denial of Service (DoS/DDoS) for the last week. Our host is still working on the issue, and has not updated us with specifics, but for now, the forums are BACK UP! Happy Posting!

and from Wikipedia on "DoS" -
In
computing, a
denial-of-service attack (
DoS attack) or
distributed denial-of-service attack (
DDoS attack) is an attempt to make a machine or network resource unavailable to its intended
users. Although the means to carry out, motives for, and targets of a DoS attack may vary, it generally consists of efforts to temporarily or indefinitely interrupt or suspend
services of a
host connected to the
Internet.
Perpetrators of DoS attacks typically target sites or services hosted on high-profile
web servers such as banks,
credit card payment gateways, and even
root nameservers. This technique has now seen extensive use in certain games, used by server owners, or disgruntled competitors on games. Increasingly, DoS attacks have also been used as a form of resistance. DoS they say is a tool for registering dissent.
Richard Stallman has stated that DoS is a form of 'Internet Street Protests’.[SUP]

computer networks, but is not limited to this field; for example, it is also used in reference to
CPU resource management.[SUP]

One common method of attack involves saturating the target machine with external communications requests, so much so that it cannot respond to legitimate traffic, or responds so slowly as to be rendered essentially unavailable. Such attacks usually lead to a
server overload. In general terms, DoS attacks are implemented by either forcing the targeted computer(s) to reset, or consuming its
resources so that it can no longer provide its intended service or obstructing the communication media between the intended users and the victim so that they can no longer communicate adequately.
Denial-of-service attacks are considered violations of the
Internet Architecture Board's
Internet proper use policy, and also violate the
acceptable use policies of virtually all
Internet service providers. They also commonly constitute violations of the laws of individual nations.
