Google's Chinese woes continue, with the search engine having been inaccessible in China for much of the day yesterday.
The New York Times reports that the disruption could have been a result of a technical change Google made – or it could have been blocked by authorities.
Users could get into the site, but received error messages if they tried to search.
Google first thought the problem was because it changed the character string it sends with search requests, but later stated it could have been caused by changes within China's systems.
Towards the end of the day, the problem seemed to be sorted out, without any intervention on Google's part.
