My dear friend Farwa, I have been hearing Steemit had been under a DOoS attack. Here is what this means:
Distributed DoS attack. A distributed denial-of-service (DDoS) attack occurs when multiple systems flood the bandwidth or resources of a targeted system, usually one or more web servers. Such an attack is often the result of multiple compromised systems (for example, a botnet) flooding the targeted system with traffic.
