All snipes that get entered are sniping correctly, and there is nothing to worry about. In fact you are safer sniping that manually sniping or bidding right now because eBay may not be up at the time you want to bid! But their bid servers are and that is how we snipe.
eBay has been having severe problems over the past 2 evenings and their site has very slow or not functional. And that since we rely on eBay to be up to keep things updated ourselves our systems have been having trouble keeping up since eBay isn't up.
You may review eBays system status messages here:
http://www2.ebay.com/aw/announce.shtml We are reworking our system so that even when eBay is down our site will still be accessible. However you probably got system busy errors today at the exact times eBay was down as is listed in their system announcement page which I linked too above. All snipes still fired, it's just the site that was busy because we were stuck trying to update bids and such when eBay was down so things got clogged.
