= Common Crawl

So far, no new domains have been found with <Common Crawl>, nor have any existing known domains been found to be present in Common Crawl. Our working theory is that Common Crawl never reached the domains <How did Alexa find the domains?>

Let's try and do something with <Common Crawl>.

Unfortunately there's no <IP> data apparently: https://github.com/commoncrawl/cc-index-table/issues/30[], so let's focus on the URLs.

Using their <Common Crawl Athena> method: https://commoncrawl.org/2018/03/index-to-warc-files-and-urls-in-columnar-format/

Hello world:
``
select * from "ccindex"."ccindex" limit 100;
``
Data scanned: 11.75 MB

Sample first output line:

So `url_host_3rd_last_part` might be a winner for <CGI comms> fingerprinting!

Naive one for one index:
``
select * from "ccindex"."ccindex" where url_host_registered_domain = 'conquermstoday.com' limit 100;
``
have no results... data scanned: 5.73 GB

Let's see if they have any of the domain hits. Let's also restrict by date to try and reduce the data scanned:
``
select * from "ccindex"."ccindex" where
  fetch_time < TIMESTAMP '2014-01-01 00:00:00' AND
  url_host_registered_domain IN (
   'activegaminginfo.com',
   'altworldnews.com',
   ...
   'topbillingsite.com',
   'worldwildlifeadventure.com'
 )
``
Humm, data scanned: 60.59 GB and no hits... weird.

Sanity check:
``
select * from "ccindex"."ccindex" WHERE
  crawl = 'CC-MAIN-2013-20' AND
  subset = 'warc' AND
  url_host_registered_domain IN (
   'google.com',
   'amazon.com'
 )
``
has a bunch of hits of course. Also Data scanned: 212.88 MB, `WHERE` `crawl` and `subset` are a must! Should have read the article first.

Let's widen a bit more:
``
select * from "ccindex"."ccindex" WHERE
  crawl IN (
    'CC-MAIN-2013-20',
    'CC-MAIN-2013-48',
    'CC-MAIN-2014-10'
  ) AND
  subset = 'warc' AND
  url_host_registered_domain IN (
    'activegaminginfo.com',
    'altworldnews.com',
    ...
    'worldnewsandent.com',
    'worldwildlifeadventure.com'
 )
``
Still nothing found... they don't seem to have any of the URLs of interest?
