i am planning to see a provider who has 40+ reviews but most recent is from Nov 07(nothing since then). her website is no longer up either. i want to see her but seem to be confused due to lack of recent review. any advice on this situation??

or she may have gone UTR but chose to leave her review history up.

 It is not uncommon for providers to take a break and take down their shingle now and then for any one of a hundred reasons.

 With 40 reviews to her credit I wouldn't let this gap overly concern you.

No reviews since Nov wouldn't bother me too much, if she has been providing long enough to have 40 reviews she has a lot of regulars which will mean that new reviews may be few and far between.  I would be concerned that her website is no longer up. Have you contacted her yet?  She may be retired.

i was able to contact her via email and seems like she is still in the business

No reviews since Nov. is no big deal, may not see that many new hobbyists anymore. But if her website is down, that is not a good sign.

Did she have an explanation as to why her site is down? Does she have an Eros or other ad running? My only other concern would be that the original gal's identity and reviews could have been hijacked. This happens more often than you might think and generally to retired ladies who had a lot of good reviews.  Without a link to her site or pictures there is no way to know for sure if the gal you are contemplating a visit with is the same lady who got all of those great reviews. Move forward carefully.
