Enom Hosted Custom Domains Showing Intermittent Connectivity Issues

We are seeing reports from owners of several Blogger blogs, published to custom domains, of intermittent connectivity problems, reported inward Blogger Help Forum: Something Is Broken.
Recently, I convey been unable to charge my custom domain weblog www.mydomain.com. My browsers (whether Chrome, Firefox, Safari, etc.) all rate me they are "unable to uncovering the server". Various online utilities study problems also. I am able to instruct to Blogger together with my dashboard for the blog, but cypher volition charge the page. All other services on my figurer look to endure working normally.

The work appears to endure somewhat intermittent together with varying across dissimilar ISPs, together with diverse online utilities which I use.

The domains existence reported all look to endure registered amongst eNom - together with at start glance, domain registration appears normal. We convey to create simply about detailed investigation to position a consistent detail, which appears to endure mutual to all individually reported domains.

At start glance, the typical eNom registered domain - fifty-fifty those amongst this reported work - appears to endure normal.
REGISTRY WHOIS FOR mydomain.com  Registrar: ENOM, INC. Whois Server: whois.enom.com Referral URL: http://www.enom.com Status: clientTransferProhibited  Expiration Date: 2013-04-10 Creation Date: 2012-04-10 Last Update Date: 2012-04-10  Name Servers:     dns1.name-services.com     dns2.name-services.com     dns3.name-services.com     dns4.name-services.com     dns5.name-services.com 

The clue to this work is seen inward the concluding sentence, inward the higher upwards example.
The work appears to endure somewhat intermittent together with varying across dissimilar ISPs, together with diverse online utilities which I use.

eNom uses v DNS servers. We tin cheque the output from each of the v servers, using the Kloth online Dig utility, together with specifying each server, inward turn.
  • Domain: mydomain.com
  • Server: dns1.name-services.com
  • Query: H5N1 (IPv4 address)
and repeat for dns2.name-services.com etc.

Running a Dig against each of the v servers, nosotros tin encounter a consistency problem. Here is a re-create of the v Dig logs, concatenated.

Examine the Dig logs from "dns3.name-services.com." together with "dns3.name-services.com.". See the reply from those servers, which returns exclusively an "SOA" for the ".com" Top Level Domain? This is consistent of a domain, improperly setup past times the registrar. In the cases reported inward Blogger Help Forum: Something Is Broken, my reply is simple.
In your case, servers #3 together with #4 create non look to properly recognise your domain. Any online service, quest either server #3 or #4 for your domain addresses, volition likely convey problems. This may explicate your inconsistent access problem. As the registered domain owner, you lot demand to contact eNom Customer Support. Show them the Dig logs from the v servers, together with inquire them why servers #3 together with #4 seem to convey a work serving your DNS addresses.
The work appears to involve domains setup on 4/9/2012 - 4/10/2012. Hopefully, plenty domain owners volition study their problems to eNom Customer Support, then this work tin endure investigated together with resolved.
(Update 6/18): With a modest but a useful diagnostic tool, to analyse DNS inconsistencies similar this.

Enom: Fix Your Dns Servers!

For over 2 months, we've been seeing reports from spider web log owners who published their blogs to custom domains, amongst domain DNS hosted yesteryear eNom, inwards Blogger Help Forum: Something Is Broken.
I bought my domain cite through Blogger,last week. It is beingness hosted yesteryear eNom. Ever since I bought it roughly of my followers, together with sometimes myself, can't access my site. There is either a DNS search or a "Ooops, Google Chrome can't find..."

I tried contacting eNom, together with they said they tin run across my site together with that all of my settings are correct. They enjoin it must live Google's problem.
The keyword hither is "sometimes".
Ever since I bought it roughly of my followers, together with sometimes myself, can't access my site.

Influenza A virus subtype H5N1 uncomplicated Dig, purchased using "Buy a domain", volition live asymmetrical aka "Google Apps".
enomhosteddomain.com. 1800 IN Influenza A virus subtype H5N1 216.239.32.21 enomhosteddomain.com. 1800 IN Influenza A virus subtype H5N1 216.239.34.21 enomhosteddomain.com. 1800 IN Influenza A virus subtype H5N1 216.239.36.21 enomhosteddomain.com. 1800 IN Influenza A virus subtype H5N1 216.239.38.21 www.enomhosteddomain.com. 1800 IN CNAME ghs.google.com. 
The problem, which non together with then many people appreciate, is that eNom uses multiple DNS servers, mayhap geographically separated. This is normal DNS hosting technique, together with guarantees redundancy if 1 information middle goes offline.

However, for redundancy to work, all DNS servers accept to live kept consistently synchronised. If nosotros attempt out the five eNom DNS servers individually, we volition oftentimes run across discrepancies.

This is 1 of the to a greater extent than subtle discrepancies, which I accept observed, inwards the yesteryear distich months - alone DNS Server #3 is out of synch, inwards this case. But that's enough, to brand the domain unreliable.
The work is intermittent. All all of a abrupt my site loads, only 10 minutes agone it didn't.
That's one eNom customer, out of over a dozen, which I accept documented. And that's 1 eNom customer, who should live complaining, to someone to a higher house eNom Customer Service.

eNom: cook your servers!


(Update 2012/07/03): Suspicion that the work is related to Anycast DNS led me to a bud, who is a immature homo TC, together with a network skillful inwards India, together with who provided an intriguing spider web log post, neatly diagnosing the underlying problem. It appears that eNom server monitoring policies may live a fleck superficial.

Custom Domain Publishing, Together With 403 Forbidden

Next to its immediate cousin error
Another spider web log is already hosted at this address
I don't know of likewise many to a greater extent than frustrating Blogger mistake states than seeing
403 Forbidden
Most cases of "403 Forbidden", seen in addition to discussed lately inwards have geographical affinity - in addition to are typically transient - in addition to utilise to blogs published to "blogspot.com".

Some cases of "403 Forbidden" however, volition involve custom domain publishing, where the spider web log possessor should - but nearly probable volition non - see
Another spider web log is already hosted at this address
When publishing the spider web log to the domain.

In simply about cases, when publishing a spider web log to an incorrectly setup custom domain, the custom domain publishing sorcerer volition neglect to discovery the wrong DNS addresses. Instead of the spider web log owner, seeing immediately
Another spider web log is already hosted at this address.
The possessor volition see
Your spider web log has been published.
Later, the spider web log possessor - in addition to all potential spider web log readers - run into the secondary symptom
403 Forbidden
.




Here, nosotros accept an splendid instance of the problem - diagnosis, in addition to treatment.

Let's get-go hold off at a Dig log extract.
jubileeventure.org.uk.    86400    IN    Influenza A virus subtype H5N1    94.136.40.75 www.jubileeventure.org.uk. 86400 IN    Influenza A virus subtype H5N1    94.136.40.75 

Now, an HTTP draw extract, showing unsuccessful access to the domain.
Sending request:  GET / HTTP/1.1 Host: www.jubileeventure.org.uk User-Agent: Mozilla/5.0 (Windows NT 5.1; rv:13.0) Gecko/20100101 Firefox/13.0.1 Referer: http://www.rexswain.com/httpview.html Connection: unopen  • Finding host IP address... • Host IP address = 94.136.40.75 • Finding TCP protocol... • Binding to local socket... • Connecting to host... • Sending request... • Waiting for response... Receiving Header: HTTP/1.1·403·Forbidden(CR)(LF) 
The solution to this work involves a touchstone misconfigured domain diagnosis (excerpted here), in addition to requires DNS address correction.
Here's what you lot have:

jubileeventure.org.uk. 86400 IN Influenza A virus subtype H5N1 94.136.40.75
www.jubileeventure.org.uk. 86400 IN Influenza A virus subtype H5N1 94.136.40.75

Google custom domain publishing requires properly setup referrals to Google servers. "94.136.40.75" is non a Google server.

Here's what you lot need:

jubileeventure.org.uk. 86400 IN Influenza A virus subtype H5N1 216.239.32.21
jubileeventure.org.uk. 86400 IN Influenza A virus subtype H5N1 216.239.34.21
