Peak 329 Mbps, lowest 48 Mbps… The 10 districts in Istanbul with the fastest and slowest internet.

Istanbul's district-level broadband speed data show a sharp digital divide, with Esenyurt reaching 329 Mbps at the top while the slowest district averages just 48 Mbps, according to the report. Users in Esenyurt, a fast-growing area with newer infrastructure, reported connections reaching 1,000 Mbps. The figures reflect Turkey's broader improvement in internet speeds driven by infrastructure upgrades, but also highlight how unevenly those gains are distributed across Istanbul. The gap matters for households and businesses that depend on connectivity, and for how operators and regulators prioritize network investment. What to watch next is whether newer housing zones sustain their speed advantage as adoption grows and whether slower districts close the gap.
