Amsterdam is home of AIX (Amsterdam Internet Exchange) and can be considered one of the fastest backbones of the internet. It was the fastest when I was working at an internet company, many, many moons ago. As far as I know, today it shares that crown with one university in GB and the city-ring around Frankfurt, Germany.
So it doesn't surprise me that any rerouted traffic ends up going through Amsterdam. Holland is also one of the countries with the highest underground cable density in the world. Only some Asian countries outmatch Holland in network capacity and prices for internet connections.Lots of US sites (and I assume other countries now as well) reroute traffic (for Europe, EurAsia, Middle East, Africa) through AIX, because Holland does it better/cheaper or just cheaper, while having excellent up-time and not so strict laws regarding content. Lets just say that Amsterdam has two red light districts...and the virtual one is a lot nastier than the physical one.
Ok, more on-topic again. A big part of all the traffic flowing through AIX consist is SPAM and whatever is being generated by viruses and malware all over the world, hence some software treats traffic coming from the Dutch backbone with a suspicious eye.
The ISP handling your traffic appears to be registered under the German flag (hence the GmbH in their name). The name EcaTel LTD doesn't ring a bell, their website gives me the impression that they manage networking hardware/servers. Likely the ISP leases their equipment.
Landlines always have preference over the lines that float in water...as "fishing trawlers" break those cables from time to time
Landlines also have more capacity, which in most cases means that your traffic can arrive faster on it's destination traveling over the whole world than through the shortest distance cable. So, at first glance, nothing too strange is going on.
However, feel free to correct me as I am not up-to-date anymore with this stuff.
Working for that internet company was really fun. About 15 years ago the main office of that company was located about 150 kilometers away from the AIX and it was already possible to burn CD's directly (at top speed) on my local PC from our servers in the AIX. Lots of Debian images passed over that line, I can tell you that.
