No. There are no bandwidth or transfer limits and we censor no content with the noted exception of filtering certain sites that are repeatedly known for offering copyrighted material that fill our mailbox with letters from attorneys. We don’t like those letters. Still, we protect your privacy, but if you generate a lot of those “lawyer letters,” we will politely ask you to leave the party.
As far as performance, we closely monitor the network 24x7x365 and ensure we keep plenty of bandwidth and server capacity in reserve for peak load times. That being said, if we detect abusive usage patterns, e.g. you’re trying to run a phone company over the VPN, we reserve the right to be unpleasant about that. Still, in years of offering VPN services, we have never limited anyone.
