Experimental research on networked and distributed systems requires a suitable research infrastructure to perform experiments. Despite past numerous efforts and initiatives, the community recognizes the obvious shortcomings of the approach and solutions that have been used until recently. A Dagstuhl Seminar was held on November 2024, discussing how to find ways to increase the value and suitability of these research infrastructures. The seminar aimed to support the research community in increasing quality, reproducibility and reuse of research results, and to allow for a more efficient use of research infrastructure resources. Moreover, research infrastructures should evolve towards advanced scientific instruments that offer a vital insight to the underlying information in improvising the understanding of science methodologies and practices as they reliably and precisely help the scientist to measure the subject of their investigations.
