Deutsche Telekom routing problems

The issue(s) with AS3320 Deutsche Telekom has been well-known for years, not only in regards to Cloudflare.

AS3320 Deutsche Telekom seem to refuse to peer directly with Cloudflare (as well as many other networks), which in the end is causing the result that traffic has to go through alternative paths (assuming such alternative paths are available, which they may not always be).

AS3320 Deutsche Telekom have similarly been in the media several times over the years, allegedly for not wanting to ensure proper capacity on their peering links, and so forth, which for example caused AS174 Cogent Communiations to send a lawsuit towards AS3320 Deutsche Telekom some years ago.

Unless AS3320 Deutsche Telekom wants to man up and participate in creating a better Internet, I’m unfortunately afraid you shouldn’t be expecting any remediation from AS3320 Deutsche Telekom (or any of it’s subsidiaries).

AS3320 Deutsche Telekom’s bad decisions is not only hitting Cloudflare, but also (many) other networks.

Tech support hosting wrote that cloudflare

Cloudflare has previously indicated that they are more than happy to establish a settlement-free peerings with other providers, and I can’t believe that DT is exclusive from that.

However, Cloudflare cannot control DT and their decisions…

@Laudian

Telekom wants Cloudflare to pay for peering, and Cloudflare doesn’t want to pay.

@Tamisoft

And this is a move only a monopoly can afford, asking money for peering.

Meta (e.g. Facebook, Instagram, WhatsApp) is likely on the way towards alternative paths too, as indicated above:

Why We're Having to End Our Direct Peering Relationship With Deutsche Telekom...

So it will be fun to see whether Meta (e.g. Facebook, Instagram, WhatsApp) will transit towards other continents as well, or still stay (quite, or perfectly) local, … going forward.
