Worked on maintaining IPTV stream accessibility in the iptv-org/iptv repository by updating streaming endpoints within the es.m3u playlist. Addressed a domain deprecation issue by systematically replacing all instances of 'ccma.cat' with '3catdirectes.cat', ensuring uninterrupted access for users and aligning with current domain strategies. The update was delivered as a focused, low-risk commit, demonstrating careful change control and clear traceability. Utilized skills in IPTV and stream management, working directly with m3u playlist files to preserve service continuity. The work prioritized minimizing user disruption and reducing potential support incidents, reflecting a precise and maintenance-oriented engineering approach.
