WordPress subdomain bypass

To avoid the issue that some IP addresses of ISP in Vietnam unable to access subdomain of ​​​`wordpress.com` (such as `ducquoc.wordpress.com`) , here is some simple ways:

 

1/ Update DNS Server: 1.1.1.1 or 4.2.2.4 or 149.112.112.112

(similar to https://ducquoc.wordpress.com/2013/04/06/dns-in-vietnam/ , the Google DNS 8.8.4.4 and 8.8.8.8 used to be good for such bypass, but now somehow it’s temporarily blocked with VNPT as normal DNS)

You might flushDNS cache on your PC, or wait 30 mins -> 3h so that the cache expires and new values are applied.

2/ Use HTTPS protocol instead of HTTP

i.e. https://ducquoc.wordpress.com , not http://ducquoc.wordpress.com

 

3/ Use some proxy servers, either web proxy, or the tools such as UltraSurf, HotspotShields, … to provides the by-pass functionality.

4/ Use some browser extensions (of Chrome/Firefox/Opera), to achieve similar functions as #2 or #3 above , basically. Some browsers like TorBrowser or CocCoc even has built-in mechanism for such.

 

** Some other work-arounds:

A/ View from Google cache (Bản lưu), if you know the full URL

For example: https://ducquoc.wordpress.com/2011/03/08/install-postgresql-database/

-> append the `http://webcache.googleusercontent.com/search?q=cache:` prefix

=> become http://webcache.googleusercontent.com/search?q=cache:https://ducquoc.wordpress.com/2011/03/08/install-postgresql-database/

(or just search Google and click on the “Bản lưu” – “View Cached” of the article)

 

B/ (Mobile browser) View from Google AMP (Accelerated Mobile Page), using either:

+ Google AMP Viewer prefix: `https://www.google.com/amp/s/` and suffix `/amp/`

=> https://www.google.com/amp/s/ducquoc.wordpress.com/2011/03/08/install-postgresql-database/amp/

(likewise: https://www.google.com/amp/s/ducquoc.wordpress.com/2017/10/15/learning-code-online/amp/ )

 

C/ Ask the blog owner to get a top-level domain (such as ducquoc.net ) and map it to some subdomain like blog.ducquoc.net , or even use that domain name to link record CNAME to the wordpress subdomain).

 

 

These ways not only work with blogs subdomain wordpress.com (e.g. blogs of professors TerrenceTao, NgoBaoChau , VuHaVan, DamThanhSon, HaHuyKhoai, TranDinhSu, etc…); but also work with of subdomain blogger.com (blogspot.com) as well.

(And these tips did work with some other blocks in VN in the past with domains of TwitchTV, Facebook, Twitter, …etc )
