Welcome to the Q&A Forum

Hi Moz, A few of our sites experienced widespread ranking drops across all keywords this morning.  Both of these are very strong sites with a high DA (56), moz rank and moz trust above 5. We haven't been doing any black hat SEO, creating spammy links, or paying for links. Is anyone else seeing anything similar or have any ideas as to what type of Algorithm update this might be? We currently rank 67th for our name. 

Because of hosting problems we're trying to work out, our domain was down all weekend, and we have lost all of our rankings. Doe anyone have any experience with this kind of thing in terms of how long it takes to figure out where you stand once you have the site back up? what the best SEO strategy is for immediately addressing this problem? Besides just plugging away at getting links like normal, is there anything specific we should do right away when the site goes back up? Resubmit a site map, etc? Thanks!
