Test your connection bandwidth with this broadband speed test, specifically for K-20 customers https://speedtest.wa-k20.net/

Please note all speedtest tools can only test the amount of bandwidth not already in use by other applications. There are many factors that can impact the test results, and a slower than expected speedtest result is not necessarily indicative of the performance of your K-20 circuit. If you suspect problems with your circuit, please contact your RITU, other internal networking contacts, or the K-20 NOC to start troubleshooting.
