During the free trial, all servers come with 1 TB of data (traffic).
After the free trial period is over and you become a paying customer, the monthly limit increases to 5 TB of data. This quota is the same for servers of all types, EXCEPT for all server configurations in the data center locations of Hong Kong, Sydney, Tokyo, and Singapore, where the monthly limit is 1 TB. Traffic quotas measure your total data usage in both directions.
If you set your server to unmetered bandwidth, you will have unlimited traffic at a speed limit of up to 50 Mbps at no extra charge, as long as incoming traffic is up to 33% of your total traffic. Please note: this is not available during the free trial period, and cannot start in the middle of the month.
