@puma: Keep cool.

-> NTT is Nippon Telegraph and Telecom, the largest Japanese Telecom company, I don't think they will appreciate that you think that they are subsidiary of Deutsche Telekom. The turnover of NTT is about twice the turnover of Deutsche Telekom. NTT Communications is the largest operator of data nets in the world.

-> With my prior ISPs I have also had occasional routing problems. Last time I switched my broker access point from NYC to Switzerland, as the broker has its own telecommunication lines. If you access routers in the US you should always have a backup connection and not cry, if the primary data feed has a few interruptions.

-> Deutsche Telekom has a open forum, where the matter is discussed. They have answered the questions. Here is the feedback given by Deutsche Telekom

January 22: DTAG confirms that there is an open ticket since January 16, also they confirm that my problem is identical to the problem related to NinjaTrader/Zenfire. They ask not to open any new tickets as there is an open ticket for the routing via NTT.

January 23: Other users confirm that there problems are related to the Telekom routers that we have identified
(80.156.161.46 + 80.157.128.30)

January 23: DTAG says that the problems are not caused by a bottleneck, but they confirm that there is a problem.

January 24: DTAG says that the problem was caused by NTT. From "was caused" I assume that it has been partly fixed.

January 24: A few users confirm that the case has been fixed. However, there is a gamer complaining that she has to wait half a minute until the monster reacts. May be the monster is not allowed by the Godzillas of the Japanese network.

January 24: DTAG says that they have still found lost packages and that the cause lies with NTT Communications.

I have found that there is a net improvement. While it was impossible to download data from the 7ticks.com server during afternoon and evening hours prior to January 23, I have now identical download speeds whether I use Telekom or Telefonica as ISP.

I cannot tell you though whether the monster is still stuck somewhere in the line.

TY for the facts Fat Tails.

I must say I am never cool when I am confronted with bad customer support. ( Thats why I have a terrible life, being in Germany lol)

DTAG support continues to reply to me with "no known problems".

On my end the problems are unchanged : I monitor the connection to 80.156.161.46 nonstop since eurex open. I have 25% packet loss . Similar numbers yesterday.

PS..: I ordered & installed the backup connection you recommended - TY This is very good , but only for emergencies - not for my day by day trading

PPS.: I monitor the connection to 64.202.118.181 and in between 80.156.161.46 shows the problems.

I am not sure that we can correctly measure package loss with ping plotter. Some servers - this is true for the 7ticks.com server in Chicago - show as destination unreachable, which means that they simply do not return the pings.

they are set up not to respond to pings - a security measurement ( anti-ddos according to Ninja ). That is ok.

But the problem lies in between. This is shown by a trace.

Ninjatrader then is confused by the high delay times and-or by the package losses.

This morning I am routed via 80.157.128.230 to 7ticks.
No packet-loss so far - but this was always so in the morning.
The problems start usually around 19:00 - 20:00 CET

The countless interruptions to Zen-Fire I had each day in December and January are gone since last Thursday (24 January).

No issues lately.

So I can confirm DTAG and/or NTT at least partly fixed the issues.

Hey guys,

thought the probs were solved?!

In my case, everyting is still fine with DTAG and Zen-Fire.

@Ribben

Did you try a different PC / Laptop?

Can you check your connection via a different ISP?

Take your PC to a friend and try to log in to ZF/NT.

I am wondering because everyone else is fine after DTAG solved the issues.



P.S.: Wäre schön wenn du das nächste mal mit Absatz schreibe kannst. Das macht das Lesen wesentlich erträglicher!

@Balanar

Hello!

No, still facing disconnection problems. 3 times yesterday and today only ones yet. As I wrote yesterday I am not a

customer of DTAG now, thus, any improvements there will not affect me I guess. I did sent a ticket to my ISP and

still waiting for a response.

I have the possibility at least going to another PC. An alternative line! Nothing to compare but a mobile connection.

I am sure nothing for testing or to work with it a complete day. I will take the points you mentioned in

consideration and will keep this issue updated.

Thx.

I had no disconnects yesterday.

But the package loss from the problem IP was even higher.

I had a good day in the past - I am not willing to say that the issues is solved yet.
