How do you know if an DDoS attack is happening?
Not all disruptions to service are the result of a denial-of-service attack. There may be technical problems with a particular network, or system administrators may be performing maintenance. However, the following symptoms could indicate a DoS or DDoS attack:
* unusually slow network performance (opening files or accessing websites)
* unavailability of a particular website.
* inability to access any website.
* dramatic increase in the amount of spam you receive in your account.
