Accessing UO Technology Resources while Traveling


Generally, most technology tools and services are available globally. There are, however, some nations that block traffic to and from specific services, and the United States maintains sanctions against certain countries that prohibit network communications. The U.S. Department of the Treasury maintains information about sanctions at the Office of Foreign Assets Control (OFAC).

Overseas users should try service-specific access workaround procedures, if available. Most of these tools will work most of the time. However, times may arise when some of these tools are not available depending on geographic region, most often those that include real-time sharing and drafting functionality (Zoom, Duo, and Microsoft 365 are the core tools most frequently reported as not working).

There are many reasons for service unavailability. While faculty, staff, and students can access technologies for educational purposes in restricted countries as per U.S. law, using a virtual private network (VPN) as a workaround, you should be cautious since it may violate local laws and regulations. Suggested alternatives include using a different tool, as described below, or employing adaptations through curricular and pedagogical flexibility.

Duo (Two-Factor Authentication)
