Common Billing Questions about NUBB

Answer your questions about Network Usage-Based Billing (NUBB).

This article applies to: NUBB (Network Usage-Based Billing)


Do I need to pay for Cornell Wi-Fi access?

For students, Internet usage to or from off-campus sites, whether via wired or Wi-Fi access, is included in network usage-based billing (NUBB).

Do I need to pay for Wi-Fi connections that are not RedRover or eduroam?

Yes. Owners of Wi-Fi access points that are not part of the Cornell system are required to pay the network usage fees for all devices using Cornell access points to connect to the Internet. Students are encouraged to secure personally-owned Wi-Fi access points against unwanted access as the owner of the Wi-Fi access point (person whose NetID registered the device) will be held responsible for all NUBB charges.

Why are wired network port charges for fraternities and sororities more than departmental port charges?

Wired network service port charges for fraternities and sororities reflect network infrastructure costs (backbone fees, etc.). Departmental ports and wired network connections in the residence halls recover these fees via other billing processes.

If someone breaks into my computer and runs up a large NUBB bill, am I obligated to pay?

Generally, yes. Please note that NUBB rates are very low and significant system abuse would need to occur over an extended period to create a significant charge. Regardless, the integrity of hosts connected to the network is the responsibility of the host owner.

What happens if someone steals my IP number?

NUBB no longer tracks individual students by IP address, but instead tracks student usage by device.  The simultaneous appearance of two devices with the same device address will usually result in an IP assignment error.  As soon as a user believes another person is "spoofing" their device they should contact their local department support provider, or CIT.  Users who knowingly spoof a device address to avoid network expense are subject to all applicable university policies.

Who do I contact with questions about my bill?

IT Service Desk

When does each billing period start and end?

See the Fees and Billing page.

How much of my monthly usage is free?

FREE monthly internet usage includes 200 GB of data.

How much do I have to pay if I exceed the free monthly usage?

Any Internet use beyond the free monthly threshold will incur NUBB charges of $0.0015 for each megabyte of data ($1.54/GB). There is a $50 monthly billing cap.

To provide some perspective, there are roughly 1,000 MB in 1 GB. One megabyte is the rough equivalent of 100 pages of text or about 10 web graphics, in terms of pages, you could view 100x1000x100 per month, or 10 million pages per month.

Video uses MUCH more bandwidth. In 2014-2015, HD video feeds have increased from 1.5G/hr to 3G/hr or 7G/hr for Ultra HD video.

Are NUBB fees restricted to certain types of traffic (MP3s, surfing, etc.), or do I have to pay for all bandwidth usage?

You are responsible for all Internet use, regardless of data type, that travels to or from your devices outside of Cornell's network. This includes (but is not limited to) email you access via Cmail, on Google's servers. Also any document storage service, such as OneDrive or Box (which recently increased storage limits to "unlimited") can quickly rack up NUBB charges if you upload or download photo albums, videos, etc. In general, fewer services are being hosted on Cornell servers. Any of these will generate NUBB applicable traffic.
