I really hope it improves though.
I was actually completely shocked when I moved to California, signed up with an internet provider, and had a technician come to my house the next day. Crazy!
(Other DSL companies can be hell, because they don't own much of the infrastructure, so you'll get stuck in endless finger pointing and shifting of blame. Cable internet providers have their own problems, but are generally a good option, as well.)
Currently work is being done to upgrade the phone network to 500/200 in the next years.
there is some DOCSIS (cable) service, mostly from Vodafone but also a smaller provider named telecolumbus.
There was versatel, but 1&1 smartly purchased it at what I believe to be an absolute steal. They have what is clearly the widest fiber network reach outside of Telekom, and 1&1 is actually going out there and selling it.
I could, if I really wanted to, get 1Gbps symmetrical for only 500EUR/month. The catch is the ~3000EUR install and minimum 3 year commitment. but, at least the option is there. Telekom, if they have fiber "available" at your address, will offer you 20Mbps for around 700EUR a month, then do this really weird delivery of an STM-1 (155Mbps) circuit, broken out into E3s (45Mbps) to a Cisco ASR1002 (a 5000EUR device, easily), that is converted to a rate limited GigE interface. Oh, and the install fee is about 1200EUR and takes a solid six weeks...but only if you call every day to remind them.
Berlin internet connectivity is a sick and twisted joke.
