Our company is hosting a website out of our office, it hosts the site, some downloads, and a ton of training videos. The server itself is a Poweredge1900, running Web Server 2008 64bit, Dual Quad Core, 16GB RAM.
The building we are in provides us with an internet connection as part of the rent. Running a speedtest on any given day usually results in at least 14Mb/s up and down, 5ms ping, so not too shabby. Out building is a sister building of a university, so its half tech businesses and half classrooms, and the bandwidth is provided by the University main building via fiber.
We are having issues with the internet being deathly slow sometimes, and our customers complaining about our training videos being choppy, slow to load, etc.. Running a speedtest during these times still results in fast speed, and low latency. The server also shows no additional load, or indication that is is having issues.
Basically, I'm fairly certain that the issue is not with us, as we have 2 different public IPs coming to us, with our back office network on one physical network, and the website all alone on its own, and performance declines on both simultaneously. How can I gather some data to prove its the connection?
