Hi Arnold, He is basically also covering the role of Peering Manager as well in his position as Wholesale Data Sales Mngt.associate Director. So, yes, I can confirm he is the Peering Manager as well. Thanks and regards, Bülent.

However, he claims that he is basically a Peering Manager. Can you confirm? Turkcell (AS34984, [0]) is our customer in Istanbul and Frankfurt and also a customer of AMS-IX and LINX.

I understand that my current title might have raised a flag regarding the "no-commercial" policy of the forum, and I appreciate your diligence in maintaining the technical integrity of the event. However, I would like to clarify that my role at Turkcell Superonline is highly technical and operational, focused heavily on Interconnection and Peering Coordination. While my title aligns with the business/account management side, my primary responsibilities for this event involve: ∙ Discussing BGP session establishment and routing policies directly with potential and existing partners. ∙ Analyzing traffic flows, latency optimization, and capacity planning for our network ∙ Managing our PeeringDB presence and ensuring technical alignment with other networks. My objective at the forum is strictly non-commercial. I am attending to discuss network architecture optimization, traffic exchange, and to meet our technical peers to improve our interconnection strategy. I have absolutely no intention of conducting aggressive sales pitches or violating the forum's guidelines. Given this context, I kindly request a re-evaluation of my application. I would be more than happy to provide any further technical details about our network strategy if needed. Thank you for your time and understanding.
