In case anyone else runs into this problem there is a way to force google-bot to re-download the robots.txt file.
Go to Health -> Fetch as Google  and have it fetch /robots.txt
That will re-download the file and google will also re-parse the file.
 in the previous Google UI it was 'Diagnostics -> Fetch as GoogleBot'.
It looks like they purchased and/or leased some address space out of Level 3's 22.214.171.124/8 block. This is a standard thing - a company with a large IP block such as a /8 (e.g. Level3's 126.96.36.199-188.8.131.52) will allocate blocks out to other companies. Level 3's had the 184.108.40.206/8 netblock for a while - since 1992 according to WHOIS. Below is an output from ...
Google has servers all over the world and uses Anycast so that a server near you answers your request, they use the same method in their public DNS product.
If you have servers on multiple geographic locations, you can set up something similiar with BIND, not using Anycast, but based on geolocation by using views for certain IP addresses.
The full list of records supported by Google Domains can be found at:
There is no 'ALIAS' or 'ANAME' or any other similar pseudo-CNAME supported.
Please note that the type of record mentioned by the Heroku documentation is not an actual CNAME, but rather an A record that is auto-updated to match some ...
I'm one of the developers on mod_spdy. At this stage the module is reasonably stable and fully SPDY/2 compliant (an earlier poster incorrectly claimed that it does not support multiplexing. That is incorrect). That said, it is not as stable as the core Apache modules like mod_ssl. I consider it a "beta" module suitable for use in environments where you can ...
No, but you can have Google Domains forward your root domain to your www CNAME.
First create a CNAME in the Custom Records section pointing www to yourapp.herokuapp.com.
Then in the Synthetic Records section, choose Subdomain forward, enter @ in the subdomain field and www.yourdomain.com in the Destination URL field.
Save those and you're done.
OK, I can duplicate the behavior (BIND 9.6), and believe I've sussed out the cause:
If you have a wildcard A record and a more specific TXT record as below the A record breaks.
*.test.bsd-box.net. IN A 127.0.0.1
www.test.bsd-box.net. IN TXT "This be a text record, mon!"
but if you have a specific A record it works fine:
I receive a reply when sending a STUN packet to port 19302 on stun.l.google.com.
Your telnet command gets no reply because it is not speaking STUN. It will attempt to open a TCP connection, which fails because STUN is running over UDP not TCP.
How Google search actually works is, of course, a closely-guarded secret.
However, in the past there has been some info coming out of them with general practices they employ.
First off, Google has hundreds of datacenters - back in 2008-ish, they were already estimated to run on several hundred thousand servers; you can safely assume they have more than a ...
Because it gets in the way of your wildcard ("*") record. If you have any records for an item, the wildcard no longer matches at all, for any record type.
From RFC1034, §4.3.3:
Wildcard RRs do not apply … [w]hen the query name or a name between the wildcard domain and the query name is [known] to exist. For example, if a wildcard RR has an ...
Why on earth would you install Google Desktop on a server? That's got bad idea written all over it. I don't mean that question rhetorically, either. I literally cannot think of a single legitimate reason to install it on a server and I'm curious about why you think your situation dictates its usage.
If the Microsoft-blessed Windows Search 4.0 isn't doing it'...
You want to prevent this sort of thing in the future? Use a real MTA instead of Google Apps. As you've discovered, it is certainly possible to relay emails through a GApps account, but it's far from ideal, and frankly, it's not what that service was built to do. They give you zero visibility into logs of any sort, which you'd need in order to troubleshoot ...
Set the fallback_transport variable to relay , that way it'll send it to Google or whatever server it should, if doesn't find the user locally.
If you never want the mail to be sent to a local user change the mydestination variable to localhost , that way it'll only forward locally email addresses ending in .localhost
It would look like that in your main....
The answer to your first question seems to be "maybe":
What file types can Google index?
Google can index the content of most types of pages and files. See the most common file types.
But the link to common files types are all text.
Even if you search for binary files like Windows Installers (.msi), you may get a link to a page containing the file ...
There are many reasons why a message might be flagged as spam. Having one domain send a message which is signed by a different domain should be more than enough to ensure it is flagged as spam. Quite simply, you need to get everything properly lined up. The signature needs to be the one for the sending domain, not the domain it is sending for. What you have ...
I have had similar few months ago. I would recommend you to send an email to email@example.com then you will get an email back containing all the results and scores. Then I think you will have a clear view of your the problem preventing your messages to get delivered to gmail inbox.
First, that SPF line is completely useless. The +all on the end means anyone can send e-mail on behalf of your domain, and it should be considered authentic. Further, that SPF record looks wrong in all sorts of ways, though I can't be sure without knowing more about your environment.
Some servers will even hold this against you. On the servers I run, if ...
The trick is to create a Synthetic Record for a any subdomain other that *.
Create the synthetic record for wildcard.domainname.com instead of *.domainname.com.
Then create a CNAME record (not synthetic) of the subdomain *.domain.com and point it to your synthetic records subdomain wildcard.domainname.com.
The placeholder subdomain wildcard could really ...
They probably have multiple datacenters in every continent, and thanks to anycasting they can announce the same networks from multiple providers/datacenters.
You will always go the least expensive path (in terms of as paths, hops, metrics, bandwidth between peers etc etc), therefor you will experience low latency from everywhere.
You can read more about ...
The error message says:
Over the last 24 hours, Googlebot encountered 1 errors while attempting to retrieve DNS information for your site. The overall error rate for DNS queries for your site is 50.0%.
This means that the problem probably lies with your DNS hosting. I ran it through DNSCheck and got this result. The relevant part is
Name server ns2....

I would revise your backup plan making sure your data is protected enough and you'd be able to restore it according to your company's RPO/RTO.
Yes you can. Don't use admin as the recipient. Use something that is "outside" like firstname.lastname@example.org.
This only works if mydomain.com is not the domain configured in Postfix. Because Postfix thinks everything is local when you configured it to be local.
You should provide WAY more information than "it doesn't work". What are your configured domains, ...
ICMP is not the correct tool for measuring network performance. A more realistic test would be using a network packet capture application like Wireshark, or something that that can perform application/protocol-specific tests, such as NPing.

Alternatively, if you want to go the Sledghammer route you can disable translation by using a Google specific meta tag:
The Via: header is added by proxies, both forward and reverse, and can appear in the request headers and the reply headers. That field containing "GWA" is notionally the hostname or pseudonym field, possibly an identifier for the proxy/firewall, e.g. "gateway A", :
Via = "Via" ":" 1#( received-protocol received-by [ comment ] )

There's no good reliable starting point for a WHOIS client. It's more or less an "illusion" that you can use whois without also specifying the whois server to query.
I'll refer to my answer here https://serverfault.com/a/615848/183318 for the available means of finding the proper WHOIS server for a TLD.
Only the method of querying IANA (WHOIS or http) is ...
