Is anyone (beside me) having issues with Sierra connectivity? It might be just me, I did some windows updates over the weekend (Win 10 Pro) and that might be the issue, but I can't connect to the Sierra Chart site, either ...

This just seems to be the historical data (which comes from Sierra) and not the CQG feed, that I use.

The error is:
DTC Client (75) | Connect event error. Windows error code 10060: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond. | 2017-06-18 18:07:21

Putting this at the top so it's not TL;DR

Hello,

We have moved to a new IP address for the server. The DNS on your side clearly has not yet updated.

I just posted about the same thing, will delete my duplicate thread.
It appears the Sierra Chart website has been down for at least the last few hours.
Inconvenient when programming in ACSIL on a Sunday afternoon!

Ordinarily all support happens through the website, so I don't even know how to let them know about the problem.
Does anyone know their direct email?

I'm not trading live so, for me, it's just a data recording issue, but you may want to contact your broker and see if they have a means to contact them.
(copied from my reply to YOUR thread )

I just checked with my broker and they don't have any information, at this time.

@MerlinT - some time last year I'd opened a ticket on their website and they reply came from [email protected]

HTH

I just shot them an email, we'll see if they reply.

I did get a reply last night, but I was already in bed:

Hello,

We have moved to a new IP address for the server. The DNS on your side clearly has not yet updated. Try again now and confirm when you can access it.

You should also still see the other server, but it would just indicate that it is in maintenance mode.

Tell us what you see now.

Thank You,
Sierra Chart Support

I didn't respond and ask them if it was a planned change, and if so, why didn't they change the TTL so customer impact would be minimal ...

This is not related to the website. It is a different issue which has been resolved.

The timeout for the SierraChart.com domain name is 20 minutes. However, it does not meant that DNS servers are going to follow this. They can use a longer time.

Here is a detailed report about the issue:
