Earlier on this year you may have noticed a "not found" error page when visiting some of the older TechNet or MSDN blogs. If you were lucky, you would have received the graphic shown below. If not, then you would have had a nice and cryptic result code...
This was due to the blog team removing those blogs which were not moved over to the new TechCommunity. Only product group and team blogs were moved over. Individual blogs were never in scope for migration to the TechCommunity. Such blogs were to be removed.
There were multiple removal phases, starting with the unused blogs. However, once the popular blogs were removed customers started to notice. Unsurprisingly, they were not happy with this…
Those blogs were subsequently re-activated due to your feedback, and the "solution" was to place the blogs into a read-only repository.
You will find that some TechNet and MSDN blogs were migrated over to the TechCommunity site.
TechNet and MSDN blog sites will be going into read-only/archive mode, effective June 20, 2019. Speaking of which, if you happened to run across any blog content you expected to find but ended up getting a default “not found” type of page, that issue should now be corrected as the blogs were resurrected. This is a temporary stay of execution though as they will be moved in the future to a static repository.
So, if you don't hear more from me you know the reason why.
