Description
Situation: Accessing IGB Quickloads has been troublesome for several members of the lab in the past few weeks. I've had issues using some of the campus wifi, and today Dr. Reid was having issues connecting while using the VPN on campus.
Task: Investigate potential network connectivity issues occurring, and maybe reach back out to whoever Dr. Loraine worked with previously to make sure that users can access the Quickloads regardless of which internet connection they're using.

My attempt at summarizing the above findings by Paige, Dylan, and Nowlan
Thank you for the summary Nowlan Freese - it is very helpful!
A couple of questions for NF:
- Clarification question: If a cell in the table is empty that means the actually was a result and the result was: "not working" ? If so, maybe instead of an empty cell, how about about "NW" for "not working."
(When I saw the empty cell, I thought that meant the combination had not been tested.)
- A technical question: For "campus computer," are we sure the person using it was able to connect using eduroam and not wired internet? If it was a computer lab computer for example, it might not be possible for an ordinary user to modify the internet settings. Maybe we need to clarify what "campus computer" means with respect to the internet connection - I assume it was ethernet?
Answer: "campus computer" = computer lab computer
Moving to Done as we have investigated the issues with network connectivity.
Ann spoke at length with Loren Striegel a network admin at UNC Charlotte after submitting a trouble ticket.
It turns out there were a number of internal network records associated with igbquickload and bioviz URLs. We were not able to figure out why some computers on some networks could not retrieve content from igbquickload hosted on the main campus infrastructure.
I added some screen captures images to this ticket showing Loren's network visualization software.
I'm on campus again and re-tried several combinations of computer+connection to try and load the various IGB Quickloads.
Connecting to igbquickload.org/quickload did NOT work on Eduroam on my laptop
Connecting to data.bioviz.org DID work on my laptop after a minute or two.
Connecting to igbquickload.org/quickload DID work on Niner-WiFi Guest.
Connecting to igbquickload.org/quickload DID work on Eduroam on my laptop this second time around.
Suggestion:
Since the student members of the group are on campus a lot, maybe we can recruit their help to investigate the connectivity problems?
They could check the on-campus wifi, with and without the VPN.
