Just like on Christmas, Googlers were working throughout New Years Day.
Truth is, I don't think any were working publicly in the support forums New Years Eve, I may be wrong. But we had Zineb Ait Bahajji and Gary Illyes both active New Years day in the forums. They posted several times, answering webmaster questions on both spam and technical issues.
Here are two of many threads:
- Delay in Webmaster Tools Updating where the response is, it is normal for their to be a delay.
- Page Not Showing Up In Google Search Results where the response was, we are not as fast as we want to be in all cases.
Of course, the Top Contributors are very active all throughout the year and basically 24/7. Google does do this often, i.e. work on New Years.
No, Google did not pay me to write this post, thanks.
