PART III – ACCEPTABLE USE AND LIMITS
Article 5. Resource usage and limits
5.1. VPS and Cloud Server customers are not subject to the sustained CPU limits that apply to Shared Hosting. The following limits still apply, however, to protect shared infrastructure:
(a) Bandwidth 95th percentile: If traffic consistently exceeds the subscribed plan, HiTechCloud may throttle the connection or charge overage fees;
(b) Anti-spoofing: forging the source IP address (IP spoofing) is strictly prohibited;
(c) Port 25 (SMTP outbound): blocked by default; opened on request once a legitimate purpose is verified;
(d) Network amplification attacks: the system automatically blocks UDP floods, DNS amplification and NTP amplification from the VPS.
5.2. Activities strictly prohibited on VPS/Cloud Server (in addition to Article 7 of the Master Agreement):
(a) Running a botnet or a C&C (command and control) server;
(b) Launching DDoS/DoS attacks against any target;

(d) Running a Tor exit node without HiTechCloud's written consent;
(e) Crypto mining on a VPS plan without a registered mining service;
