#BANDWIDTH THROTTLING SERIES#

This is a problem compounded by the fact that running OpenVPN (or SSTP) over TCP port 443 makes VPN traffic indistinguishable from the HTTPS traffic ( which uses the protocol on which almost all internet security relies. Throttling or blocking VPN traffic is very problematic, as businesses rely on VPN to secure internal communications, process payments, and for any number of routine purposes that are vital for them to operate, so banning VPN protocols would have a very negative impact on the economy. Alternatively, it can simply throttle or block all traffic connected to known IP addresses belonging to VPN providers. However… It is possible for ISPs to throttle / block VPN itselfĪlthough all data passing through an encrypted VPN tunnel is hidden from an ISP, it can ‘see’ the tunnel itself, and can therefore choose to throttle or block all such traffic. Using a VPN therefore prevents bandwidth throttling of internet services, and will likely become a vital tool in the struggle to preserve net neutrality.

Just to demonstrate how effective this can be, in July Colin Nederkoorn, CEO of Customer.io, performed a series of tests in which using VPN improved his connection speeds when streaming Netflix over his Verizon connection tenfold! Because all data passing through this tunnel is protected by strong encryption, your ISP cannot know what users are doing on the internet, and therefore cannot prioritize or discriminate against specific services. Using a VPN service connects your computer (including mobile devices) to a VPN provider’s servers using an encrypted tunnel.

How will a VPN can help bypass ISP throttling

If you just want to avoid the issues caused by ISP throttling, a VPN is the solution. We explain in further detail what ISP throttling is and why it happens in our what is ISP throttling guide, check it out.

One of the reasons ISPs do this is to save costs or because some ISPs simply cannot service hundreds of thousands with the high speeds promised. If not, is it possible to configure an app to send all traffic on a separate adapter that would have a single IP, so we could filter outbound at our router level to throttle that traffic?Īlternatively (if we're attacking this from the wrong angle), is it possible to limit Azure transfers to a maximum bandwidth allotment in some capacity? That's all I'm really after, as any other traffic should be able to use the maximum it can (meaning QoS doesn't apply - there isn't contention here, just too much outgoing in general).From our point of view, we want our internet speeds to be as fast and as consistent as possible, however, internet service providers often restrict their customer's speeds, which is commonly referred to as ISP throttling.I know in C# I can get a list of network adapters and change properties, but is it possible to tell an app that it's traffic needs to utilize a specific IP (instead of the default) for outgoing connections? We could use this to filter anything coming out of that IP, regardless of destination and only this app would use that address.

Outbound traffic on a server with multiple IPs utilizes the first IP configured as the 'main' one.Thus far it works really well, however since it is sitting in a colocation area, my bandwidth usage can hit 190mb/s+ which is a bill I'd rather not pay. I wrote a small utility that utilizes Azure blob storage to push some files across for a secondary backup (~100GB).
