Bandwidth
Bandwidth is a monthly flow that represents information on the use of the bandwidth, or the amount of data allowed in data transmission within one month. Bandwidth is counted for all server activities, ie incoming and outgoing web traffic (HTTP), receiving and sending E-mail (POP3, IMAP, SMTP), file transfer (FTP).
Your Bandwidth is reset, every month (in most data centers traffic recovery occurs on the first day of each month) and starts to count from scratch. If the allowed flow is exceeded, the user will have to charge for traffic overruns or the account will be suspended.
Can I purchase additional bandwidth?
Of course, you can purchase additional bandwidth for any of our plan, vps or cloud.
