digitalmars.D - forum.dlang.org moved to a new server

Hi everyone,

DFeed (the software running on forum.dlang.org) has been moved to 
a much faster server.

My apologies to everyone who had to endure the slow page load 
times or failures during the old server's nightly maintenance. 
This move has been overdue for too long.

The old server is now acting as a proxy, so there should be no 
downtime due to cached DNS records.

Please let me know here or on IRC if you notice any problems.

Thanks! This raises again the question whether we should consolidate 
hosting so you don't need to pay for that (bus factor etc). Would you 
want to transfer DFeed to digitalmars?

Thanks for the offer, but hosting DFeed isn't costing me 
anything, since I need this server for several other purposes. 
Besides, considering the babysitting it needs - whether it's 
killing spam, or pushing a quick fix - I'd feel more comfortable 
running it on my own server. The new server is probably quite 
beefier than the DigitalMars ones, seeing as they're not immune 
to downtime either :)

As for the bus factor - I've also copied over your SSH key, and 
all data is backed up nightly. If I can do more to increase it, 
let me know (I never got a SSH key from Walter).

Thank you! It's pretty fast now!! :)

Btw, I have been using Thunderbird and I frequently see the already read 
threads (mostly messages of the existing threads) suddenly appear as 
unread (in bold). Is this happening from your end? If so can you please 
fix it?

It quickly gets boring to read the same messages over and over thinking 
they are brand new.. Looks like some kind of synchronization problem..

Searching these newsgroups in Thunderbird now works, and it works pretty 
fast too!

I don't see how Thunderbird is related to the forum... Both 
Thunderbird and the forum software are newsgroup clients (they 
both connect to news.digitalmars.com to get and post articles). 
There is no way for the forum to know which messages you've 
marked as read, because Thunderbird does not upload that 
information to the server - it's only stored locally. And even if 
Thunderbird did upload this information to news.digitalmars.com, 
DFeed would still have to know how to ask and obtain that 
information from the server, and identify you among other users 
(which would be tricky, considering you don't need to provide any 
identifying information to download articles)...

I suppose that DFeed could have its own NNTP server (similarly to 
what Vibe.news does), allow logging in with the forum 
username/password, and mark messages downloaded via NNTP as 
"read" in the web interface...

Again not sure how that's related...

Don't forget to extend the NNTP protocol to include this information, 
and then get Thunderbird to support it ;)

Well, with the old server I often faced XHR (XMLHTTPRequest, I suppose) 
errors on Chrome (Win7), especially at night (UTC +1). With the move to 
the faster one, I've never succeeded in retrieving a single post. So 
I've gone back to Thunderbird, which works beautifully, BTW.

Oh, and it's not so easy to find the name of the news server on the website.

Could you please post which web browser and version you're using, 
and if you could be troubled, a Wireshark capture of a failed 
attempt to retrieve a page?

On the forum index, there is an "Also via" column. That contains 
NNTP links.

I've also experienced such behavior. Some image with worms (502 
error, I guess) on every thread. The issue was resolved when I 
cleaned up all the dfeed cookies.

If that happened around 18-19 UTC yesterday, there was about 10 
minutes of downtime as I was fixing mailing list retrieval. If it 
happens again, and you can access the forum from another browser 
or a private tab, please post here with your web browser and 
version, and if possible, a Wireshark capture.

Ah, thanks for the tip, cleaning the forum cookies has resolved the

Chrome Version 26.0.1410.64 m

Updated to Version 31.0.1650.63 m (latest), but it didn't change anything.
