Google crawling way more than normal.

[vboard22]

Hi guys,

My site hasnt been indexed in google for a while, I did some changes, last 2,3 weeks. I notice that Google crawl a lot more lately to mysite.

Here are some daily data:
2006-06-21: 1
2006-06-22: 1
2006-06-23: 10
2006-06-24: 28
2006-06-25: 209
2006-06-26: 234

Is this a good sign? Does it mean my site was in "sand box" and may be able to be indexed?
