We're no longer turning up in Google SERP for our brand search when we used to be #1 after our site update. Any ideas why?

We recently updated our website and during the push,  someone mistakenly 301 redirected "www.brandx.com" to "brandx.com" instead of the otherway. Since then, our website no longer turns up for the search "brandx" on Google. We have reversed the mistake a few days ago, but we're still not turning up, and we used to rank #1 in Google SERP. Could it just be due to timing between the crawls and that our www. site didn't make it in Google's index due to this mistake? We have submitted our new sitemap to google a couple of days ago as well, as a side we're still showing up #1 in Bing's results however. And it should still show up based on SEOMoz's SERP report.

Any help would help as I'm growing increasingly concerned.

I have seen this happen before. Yes, wait a few days before panicking. It takes time when something changes for the index to update. It could be a few hours or a few days. If you don't reappear in a week, then it might be worth investigating further. I wouldn't make any more significant changes right now. Wait it out first.

OK you can redirect www to non www, or non www to www. Google is fine with either way so that is not technically a mistake unless you have domain associated set in WMT for www - then this is an issue because you are sending mixed signals.

Verify both www and non www versions in WMT like they are two separate sites, then go into the non www site account and request it to be removed from Google's index to help speed up the process.
