Back Online - All Mission Critical Components Working

[Greg Bernhardt]

That wasn't soooo bad know was it? All mission critical components are working. LaTeX as we suspected before the move is not working. We'll look into this ASAP. So no LaTeX for right now. Please let us know if anything else is broken. Enjoy the new home and please share with us your survival stories!

It's good to be back. And no, that wasn't so bad at all: we were down for less than 24 hours. Thanks for your hard work, Greg.

One thing I've noticed: the PhD comic feed doesn't appear to be working properly.

 

[Astronuc]

Thanks for the great job, Greg!

I'm not quite back. I used the IP address access PF, since the url is not updated locally (NE US). The regular skin is not working, and all the buttons show [physicsforums.com]. Nevertheless, I can read and post.

 

[Evo]

Great work Greg, I'm also using the IP address. Everything looks like it made it!

 

[Hootenanny]

I'm using the IP adress also, so no style sheets and images (except for the PF bar at the top), but at least we're back. Thanks Greg

 

[Evo]

If you click around, everything appears normal. It was only two pages that didn't look right.

We've been online for a couple of hours and only 19 people, 6 members, 4 mentors and 9 "guests", half of which are search engine spiders.

It's all quiet and spooky walking around in here.

I've just got in by going to "physicsforums.com", which now seems to be resolving to 74.86.200.109 from here, but "www.physicsforums.com" still seems to be resolving to the old address and is now not even showing the vBulletin message, but is simply not responding.

 

[Evo]

Yes, I'm getting that also. It will take time to resolve.

 

[Astronuc]

Ah - the PF.com works but the www.pf.com url doesn't.

Using the IP address, I can access the forum, but I can't see the avatars or any of the buttons. With the PF.com url, I can see buttons, but the top of the page shows lines of [physicsforums.com] rather than the banner.

 

[Evo]

Both the IP and just the "physicsforums.com" work fine for me. I can see everything normally.

 

[Astronuc]

I just came in on my laptop, and PF looks like its normal self.

 

[Math Is Hard]

Hi! I made it!

I used https://www.physicsforums.com/

 

[Math Is Hard]

Congrats, Greg! You make it look easy.

I had a connection issue that turned out to be because https://www.physicsforums.com/ now lacks the www alias. Nothing works if I try to use https://www.physicsforums.com/ but drop the www and it's flawless. Using the IP address works but lacks the style sheet.

Users that are trying to use their bookmarks with the www will not be able to access the forum. You need to get with an administrator that has access to the MX records to fix this. Meanwhile many people will not realize the site is back.

This is not a glitch, the DNS is propagating. This means the addressing link from the www address to the IP address is not fully functional everywhere. This can take up to 72 hours for some people.

The www is an aliased subdomain. If there is no www subdomain pointing to https://www.physicsforums.com/ then it will not work no matter how updated the DNS servers are. The very fact that https://www.physicsforums.com/ works tells me that at least in my case the DNS pointers are updated so if the www alias existed it should work because it is the same pointer wrt DNS controllers.

Adding the www alias should fix https://www.physicsforums.com/ immediately for anybody that can access the forum through https://www.physicsforums.com/.

Thanks, Greg, Way to go, I spent my time http://www.thescienceforum.com/mammoths%2C-lice-in-the-fur-of-climate-claims.-14901t.php .

I think I'll run a similar thread here later.

LaTeX as we suspected before the move is not working. We'll look into this ASAP. So no LaTeX for right now.

I have to start reading these announcements more carefully. I just spent 20 minutes trying to figure out why Latex wasn't working. :uhh:

The www address is already working for people where DNS has been propagated, Greg has said it will turn up for different people at different times.

Greg has done this several times, if any glitches linger, he will take care of it, he knows what to do.

Working on the DNS problem.

We'll see. DNS doesn't even pay attention to the www part. It routes to the domain controller based on the physicsforums.com part and the domain controller routes for the subdomains. The only reason it takes time for DNS to update is because non-authoritative DNS servers have the old IP in cache. This cache is only the pointer for physicsforums.com and not the subdomains.

In fact I just ran a trace on both physicsforums.com and www.physicsforums.com. They resolve to separate IP addresses but both IP addresses belong to SoftLayer Technologies Inc. So I am in fact being routed to the right server in both cases but the alias is still not working.

Alloha

Thanks' to Andre for letting me know about the non-www address.

Still, I am enjoying my chat-free night and watching snooker Posting only in commercial breaks.

 

[Kurdt]

Thanks Andre. We've been up ages and I missed all this time

 

[Evo]

Thanks Andre. We've been up ages and I missed all this time

I was going to e-mail you this morning, but I was sure cristo or Hoot had given you the key.

 

[Kurdt]

I'll have to have a word with those two.

Well, Greg is working on it. I got the same results you did earlier today. Usually when mx records didn't get changed, I had to have my client contact Network Solutions, it was usually something missing on the form. It's been over two years since I've gotten involved in a switch of ISP's which changed the IP address.

 

[Borek]

Just remembered. For SEO reasons it is advised to redirect 301 all pages to either www or non-www version. Not sure if it is still an issue, I suppose it may be. Won't be wise to change it right now, but Greg may want to clean it up later.

Google has a setting in it's Webmaster Tools suite that allows you to force google to use one or the other.

 

[Borek]

Sure, forgot about it. I am redirecting, so I never needed that

 

[Moonbear]

What a relief! I've arrived home from my weekend away and PF is back up. That was relatively painless, though when I had too much free time last night, I did end up having to buy a lame book from a CVS to read. (Unfortunately, I couldn't meet up with hypatia to form a PF withdrawal support group since all her PMs responding to me telling her I'd be in her area this weekend were trapped in the server move. )

I did go apple picking and got myself lost in a corn maze. *hands out apples*

So, I was well prepared with my bushels of apples as rations in case the lights didn't go back on. If PF was still out tonight, I think my co-workers might be enjoying some apple pies by tomorrow. (Actually, I'm not going to start pies this late in the day, but that's definitely next weekend's activity plan.)

 

[G01]

Glad the move went well, without too many big issues. I had no trouble getting on to PF.

I didn't even have time to get bored this weekend! So, it was a good weekend to move.

 

[mgb_phys]

A whole 2 days without PF - do I get to go on Oprah and relive my experiences?

 

[Borek]

www version working for me.

 

[Evo]

www version working for me.

It's still down for me. Hey, why did you get fixed first?

 

[cristo]

Mine was fixed a while ago, too.
