Girlfriend staying out till 5am?

Girls... am I being irrational or not?

My girlfriend (39) & I (46) are at the 10 month mark.

In short, when she goes out sometimes it's untill well past 2am. Most of the time it's 3-6am. She says everything is okay, she's safe, she's with friends, she's with couples, etc.

I don't need to know what she's doing every minute of the day/night, and I don't want her taking time away from her friends just to satisfy my curiosity with constant updates. I'm not a jealous man, but I'm very protective by nature and she is fully aware of this. To her credit she's doing better at including me (via texts & videos) in her partying since we discussed things a few months back. But... when she goes out there always seems to be SOMETHING that introduces a break in the communication during the night. This last time (last night) it was a cellular provider outage that effected a vast region, aka bad signal, so messages couldn't go through for 4+ hrs. The time before that it was a dead cell phone, the time before that she lost track of time.

These things are circumstantial and aren't really what bother me. If they ended with her safe at home at a decent hour I wouldn't be writing this post. However each one ended after 5am...

So my question is this: Is it normal for a partner to stay out this late?

Now, some more details:

1. We're in a LDR. I live in Cabo and she lives in Guadalajara

2. I'm American, she's Mexican

3. She's has a VERY exotic look, I mean drop dead gorgeous. By all rights well out of my league.

4. She lives, and goes out, in a very dangerous city. Kidnappings are commonplace, her ex was abducted twice for money.

I worry dearly for her safety. She tells me where she goes, but as we know plans change, after parties etc. I don't know who she's with, where they're going, is the cab driver is safe, if she's monitoring her drinks, and a hundred other things.

I'm sure I'm leaving some details out, so if you need any more info before advising anything, feel free to ask.

I'll add that this is the 1st relationship I've been in in well over 10 years, so I'm a little rusty with this whole dating thing. I don't want to cast her in a bad light, I just want clarity. I also understand there are cultural differences at play here and I'm working hard to keep those differences in mind before making any harsh decisions.
