Welcome to IWETHEY!

New Need a favor, who can see my blog?
I just got a third report this morning that someone can't see my blog. All three people have said they can see the main site -- http://cooklikeyourgrandmother.com -- but not the subdomain with the blog -- http://blog.cooklikeyourgrandmother.com

The subdomain is hosted on Blogger via a cname entry. I can't figure out where to look, so I'm hoping someone out there can't reach the blog. I need someone who's seeing the problem to ping it and tell me where it's trying to get to.

New no problem from the corp IP addy
will try at home later
New Both load immediately from here.
Firefox 2.0.0.12 on OS/2 from Los Angeles County.
New Fine
Firefox over comcast in NJ
New Ye-gads this is frustrating
This is the worst part of intermittent problems, sitting here wishing it would break and it won't.

Would a tracert help track this down?

Apparently a "Layer 4 Tracert" is the most modern tool - http://pwhois.org/lft/index.who (I don't see a Winders binary, though). (via http://en.wikipedia.org/wiki/Traceroute )

Dunno if this IPTrace thingy would help either:

http://www.ip-adress...urgrandmother.com (shows up as Kansas)

http://www.ip-adress...urgrandmother.com (shows up as SF).

HTH a little. Good luck.

Cheers,
Scott.
New Fine for me
New OK here
is it possible they can't see it because they're at work? ie: blogger.com is filtered as a non-work-related site?
New No
At least one of them was able to comment on the blog. They went to a Google cache of one of the posts, clicked the "Comment" link, and up popped the comment page which is at blogger.com.

That means, as far as I can tell, it's something in the DNS that's not working. And I can't trace it from here, because for me it is working.

New I had a DNS problem a few weeks ago.
The aaxnet.com site disappeared. I called OC Hosting and the support guy didn't even recognize the ocservers.com DNS servers I'd been using ever since the transfer from Velocity. He had me change them to carrierzone.com DNS servers at Network Solutions.

I could access the aaxnet.com site from my LinkLine DSL service in less than 20 minutes, but it was 3 days before I could send emails from my clovegarden.com account (hosted with HostUltra) to my aaxnet.com account. Clearly, when DNS goes screwy, it can take quite some time for the kinks to work out.
New It's the scope of it that's confusing the hell out of me
One report from Texas, one from Slovenia, and one from right here in Cleveland. Obviously there could be lots of other people who aren't seeing the site who aren't telling me about it.

Drew
New Does this help? (More)
It sounds identical to your problems, but this time with Amazon's S3:

http://developer.ama...=34076&tstart=150

[edit:] Yet more gotchas that may or may not apply: http://www.dns.net/d...tml#cname-targets

Dunno if any of this is helpful. I found these links by searching on "dns cname not propagating" (without the quotes).

Good luck!

Cheers,
Scott.

New Re: Need a favor, who can see my blog?
I can see it fine on Firefox west of Chicago




"Chicago to my mind was the only place to be. ... I above all liked the city because it was filled with people all a-bustle, and the clatter of hooves and carriages, and with delivery wagons and drays and peddlers and the boom and clank of freight trains. And when those black clouds came sailing in from the west, pouring thunderstorms upon us so that you couldn't hear the cries or curses of humankind, I liked that best of all. Chicago could stand up to the worst God had to offer. I understood why it was built--a place for trade, of course, with railroads and ships and so on, but mostly to give all of us a magnitude of defiance that is not provided by one house on the plains. And the plains is where those storms come from."

New good from comcast at home
New Okay, got a couple of leads
http://www.checkdns....er.com&detailed=1
CheckDNS.NET is asking root servers about authoritative NS for domain
Answer from ns1.abac.com: domain 'blog.cooklikeyourgrandmother.com' not found

Okay, so it seems to be at my host. Log on to the control panel and ...
IMPORTANT: Your account is in process of being migrated.

Any changes to your account, except for payment related information and support tickets will be disallowed until the migration is complete.
Please note that access to all your hosting tools, except for webmail will be disallowed as well.

Oh yeah, they're upgrading the hardware. But they specifically said DNS wasn't supposed to be affected. On hold with their support number now, we'll see how that goes.

New if they are migrating to another IP
then it will need to propagate, can take from 24 hrs to several days
New Just got off the phone
There's no reason this should have broken. They're moving my nameserver to another box. Okay, no problem.

Set up the DNS records (including the cname) on the new box.
Set the TTL on the old box to 5 min.
Reset the entries on the old box to set the new one as authoritative.
Leave them both in place for several days.
Kill the old box.

Am I missing something? I'm not a networking guy, but I thought this was a solved problem.

Drew
New I suspected this.
Anytime things are moved... GLUE records are required to do it seamlessly.

If they don;t add in the Glue Records for *ALL* the possible entries, and especially things like CNAME entries get confused.


Just do you know they only have a Glue record for ns1.abac.com not for ns2.abac.com (in fact ns2.abac.com is showing any IP address when a whois is done)

I use Aplus for my domain name stuff... but host my own DNS authoritative server, to avoid these type of things.

I also use dyndns paid secondary DNS hosting for scalability.

Good luck. DNS is picky, especially lately with all the attention its been receiving about DNS SEC and the problems being caused by people trying to poison caches to exploit IE browser phishing hacks.

If you do a "whois -H gregfolkert.net" you'll see the glue records as listed as my secondary DNS provider also publishes them directly as alternate IPs.


whois -H gregfolkert.net
[snip]
Domain servers in listed order:
ns2.mydyndns.org 209.69.32.138
ns3.mydyndns.org 66.37.218.208,64.71.191.27
ns4.mydyndns.org 212.100.224.176
ns5.mydyndns.org 66.37.218.208,66.151.188.46
uno.gregfolkert.net 208.64.37.170

New Supposedly they have glue records
http://www.robtex.co...com.html#analysis

That shows ns1.abac.com and ns2.abac.com being exactly the same. Looks like they're consolidating down to the one server ns1.aplus.net.

And should I be seeing the cname for the subdomain in that list?
--

Drew
New Not in that one...
But this one

http://www.robtex.co...com.html#analysis


I guess they do include everything. Oh well. I'm out of ideas.
New Probably just hasn't propogated everywhere yet

Followed my GPS, now it keeps saying "Can't get there from here". I guess I'm stuck ;-)

New Welcome!
Burlington area?

New Thanks!
Middlesex, just north of Montpelier.
New That is a beautiful area.
In a month or so, the fall foliage will be truly amazing. The hardwood trees, particularly the maples, produce a great variety of bright colors from light green, to yellow, to orange, to deep reds. If you have never been to the New England states in the fall, you are in for a treat.
Alex
New Ah yes, leafpeeping season...
The others being mud season, blackfly season and winter ;-)

I have done a stint in this area before, only not as a permanent resident.

New Both work on Cox in VA.
Oh, I'm using a non-default DNS though. (Thanks again, Greg.)

Cheers,
Scott.

New works with Cox dns as well :-)
New Fine by me.
Still have yet to come close to my cap
New Both okay from the Land Down Under.
However, I am atypical: I have my own DNS server which looks things up from the root. And I don't visit your sites daily, but I have visited in the last two weeks.
