Datayze.com and Countdowntopregnancy.com both down

I’ve used both of these sites so much the last year while TTC. Their calculators are so helpful and reassuring (miscarriage odds reassurer (Datayze), intercourse timing, pregnancy test timing, symptom data and so much more on countdowntopregnancy.com). It seems that both sites are now inaccessible for whatever reason. Has anyone else had the same issue? Really hoping they come back!
