In 1991 the NSFNET backbone service was expanded to additional sites and upgraded to a more robust 45 Mbit/s (
T3) based network.
The new T3 backbone was named ANSNet and provided the physical infrastructure used by Merit to deliver the NSFNET Backbone Service.

Livingston Enterprises. The NASs supported dial-in access separate from the Merit PCPs and SCPs.
In 1993 Merit started what would become an eight-year phase out of its aging PCP and SCP technology. By 1998 the only PCPs still in service were supporting Wayne State University's
MTS mainframe host. During their remarkably long twenty-year life cycle the number of PCPs and SCPs in service reached a high of roughly 290 in 1991, supporting a total of about 13,000 asynchronous ports and numerous
LAN and
WAN gateways.

In 1994 the Merit Board endorsed a plan to expand the MichNet shared dial-in service, leading to a rapid expansion of the Internet dial-in service over the next several years.

In July 2007, Merit decommissioned its
dial-up services.
During the 1970s, 1980s, and 1990s Merit operated what is known as a "
value-added network" where individual data circuits were leased on a relatively short-term basis (one to three or sometimes five years) from traditional telecommunications providers such as
Ameritech

,
Sprint, and
MCI and assembled into a larger network by adding routers and other equipment. This worked well for many years, but as data rates continued to increase from kilobits, to megabits, to gigabits the cost of leasing the higher speed data circuits became significant. As a result, the alternative of building its network using "
dark fiber" that Merit owned or leased on a relatively longer-term basis (10, 20, or more years) under what are known as "
Indefeasible Rights of Use" (IRU) as well as using or sharing fiber that is owned by its members became attractive.
Merit's statewide fiber-optic network strategy began to take shape when:
* in 2003 a fiber ring was deployed in
Lansing;
* in 2003 Michigan State University, the University of Michigan, and Wayne State University launched the Michigan
LambdaRail Network (MiLR) project to link the campuses to each other and to Chicago using privately owned fiber, with Merit to operate MiLR on behalf of the three universities and using some of the MiLR fiber for its own network;
* in 2004 fiber rings were added in

During 2016, Merit added new publicly accessible hubs of the Michigan Cyber Range in Southeast Michigan. Cyber Range Hubs opened inside the Velocity Center at Macomb-Oakland University in Sterling Heights on March 18 and at Pinckney Community High School on December 7. Each location provides certification courses, cybersecurity training exercises and product hardening/testing through a direct connection to the Michigan Cyber Range.
In 2016, Merit began one of its largest projects; managing the implementation of the Michigan Statewide Education Network (MISEN), a private transport based network. MISEN connects 55 of Michigan's 56
Intermediate School Districts (ISDs) via high capacity fiber infrastructure. The project was completed on June 30, 2017, and the result was a 10 Gb connection to each ISD as well as a 100 Gb resilient core. Merit continues to manage MISEN, which gives Michigan ISDs the ability to leverage the multi-gigabit infrastructure for services like Internet access, student information systems, and other critical services, putting Michigan's schools at the forefront of technology and innovation. Throughout 2017, Merit has continued shifting their strategy to focus on network, security and community. They are now considered one of the national leaders in cybersecurity.
In 2019, Merit launched the Michigan Moonshot, an approach to impact the digital divide statewide.
In 2019, as part of the Michigan Moonshot, Merit partnered with national broadband organizations (including the Michigan Broadband Cooperative, Next Century Cities, and the Institute for Local Self Reliance) to create the Michigan Moonshot Broadband Framework''.'' This crowdsourced document will serve as a community network primer and the basis for planning a community roadmap. Contained within, a reader will find overviews on policy and technology, community success stories, links to myriad resources and planning tools from national broadband leaders and a phased plan for building a regional network. While much of this information exists in locations across the web, this unique curation was carefully designed by leading experts to serve as a comprehensive playbook for communities that are committed to improving broadband access for their citizens.
In May 2019, Merit Network, in partnership with Michigan State University's Quello Center and the D.C.-based Measurement Lab, launched a pilot for the Michigan Moonshot broadband data collection project. Three school districts, representing more than 6,000 students, were chosen. The data for this project consisted of three databases linked by a unique de-identified participant ID; including a paper survey completed by all students age 13 and older, student records (i.e., M-STEP scores) that were de-identified and results of an Internet speed test that students completed on a website using any device they used to complete homework.
Armed with an accurate picture of Michigan's connectivity, blockers to broadband network deployment in rural communities could be reduced through a combination of techniques. Pilot project findings are expected to be released in late fall, 2019.
On May 30, 2019, Merit hosted the Mackinac Policy Conference Session as part of the Michigan Moonshot initiative. President and CEO of Merit Network Joe Sawasky moderated a panel that featured state, regional, and national thought leaders, including: Dr. Johannes Bauer, Quello chair for media and information policy and chairman of the department of media and information at Michigan State University, Lt. Governor Garlin Gilchrist II, and Marc Hudson, founder and CEO of Rocket Fiber.
In October 2019, Merit's president and CEO, Joe Sawasky, joined Former FCC Commissioner, Mignon Clyburn, Jonathan Sallet, senior fellow at the Benton Institute, Larra Clark, deputy director at the American Library Association Public Policy and Luis Wong, CEO of the California K-12 High Speed Network for a panel discussion, Broadband for All in the 2020s at the 2019 SHLB Coalition’s Anchor NETS conference.
In 2019, Jonathan Sallet, Senior Fellow for the Benton Institute for Broadband & Society, published Broadband for America’s Future: A Vision for the 2020s. The purpose of this document is to collect, combine, and contribute to a national broadband agenda for the next decade. As the most transformative technology of our generation, broadband delivers new opportunities and strengthens communities. The Benton Institute upholds a commitment to changing lives and advancing society through high-performance broadband connection, which will bring remarkable economic, social, cultural, and personal benefits.
In 2019, Merit's Chief Information Security Officer role grew into an executive position, overseeing the Michigan Cyber Range and Merit's security division. Kevin Hayes has served as Merit's CISO since 2018.
In 2019, Merit Network partnered with MISEN (Michigan Statewide Educational Network) and MAISA (Michigan Association of Intermediate School Administrators) to develop Essential Cybersecurity Practices for K12. This guide translates the CIS Top 20 Security Controls into achievable actions that school IT staff can accomplish.
On October 19, 2019, Merit Network relocated from 1000 Oakbrook Drive in Ann Arbor, MI to 880 Technology Drive, Suite B, Ann Arbor, MI 48108. The 880 building provides a collaborative space with increased community access, including additional space available for rent by outside organizations.
On October 28, 2019, the Michigan National Guard and the Michigan Cyber Range hosted an International Cyber Exercise as part of the state's North American International Cyber Summit. Eleven teams from five countries and six states competed in an all-out, fast-paced cyber exercise that resembles the physical game of paintball.
