Starlink has been shown to exhibit a periodic pattern with a characteristic throughput drop on the boundaries of 15s intervals. A multitude of prior works hypothesize various root causes for this pattern, such as reordering and packet loss. Some works have attributed these effects to the edge router, advocating for explicit feedback to the transport layer. However, with the edge router being a proprietary Starlink device, it raises questions about the extent of its influence on periodic throughput drops, losses, and jitter, leaving us to wonder if we fully understand the underlying issues.  \nThis paper presents the first measurement study with avantage point that is by far the closest (last hop) to the core Starlink network. We use a Generation 1 dish, which allows us to bypass the proprietary Starlink router and connect a Linux server directly to the dish. We investigate the impact of the edge router on the observed periodic pattern in Starlink performance. Our results are primarily negative in terms of any significant buffer buildup and packet losses at the edge router, suggesting that the causality of the observed patterns lies entirely in the core network, a proprietary space that cannot be fixed by the end user. Interestingly, we observe similar patterns even with a constant bitrate UDP sender, likely indicating that the periodic drop in throughput is not an inherent limitation of existing TCP implementations but rather a core network characteristic!  \nPermission to make digital or hard copies of part or all of this work for personal or classroom use is granted without fee provided that copies are not made or distributed for profit or commercial advantage and that copies bear this notice and the full citation on the first page.

Several breakthroughs in technology have enabled this growth, including the development of the TCP/IP protocol suite, broadband connectivity to end-user homes, and wireless technologies such as WiFi and cellular networks [9] . Yet, even after five decades of technological advancements, providing high-speed internet access to all corners of the world remains an economic and technical challenge[3] .  \nLow-Earth Orbit (LEO) satellite networks have emerged as a promising solution to this challenge, offering internet access to remote areas, even during disasters [19] .
