Cannot Access Website Over Fios Connection

Enthusiast - Level 2

I'm hoping you can help me with something that's beyond my skill level. 

I suddenly cannot access www.dokuwiki.org over my Verizon FIOS connection. When I try, it just times out. Running the suggested Windows networking troubleshooter, it says dokuwiki.org is available, but not responding to requests. 

Alarmingly, once in a great while when I try to access dokuwiki.org over FIOS, I get a malware site! I'm positive this is not due to a typo, there's something funny going on.

Also, if I first set up a VPN connection, or if I use my work VPN, I can access dokuwiki.org just fine. 

Same is true on my cell phone. If I try dokuwiki.org when the phone's connected to my FIOS WiFi, it times out or, occassionaly takes me to a malware site. If I turn off WiFi and use the cell phone's T-Mobile cell network, I can access dokuwiki.org just fine. 

Clearly something is wrong, and based on the test with my cell phone, I don't think it's my setup. I think there's something wrong on the FIOS network somehow. 

But I don't know enough to pinpoint the problem. Also, I don't really know how to report it to Verizon w/o spending hours talking to tech support people who just want me to unplug and re-plug in my router. 

Any thoughts? 

Thx!

Okay, waited 2-3 days and now it's working w/o any changes on my part.

To reiterate, last weekend I tried to reach www.dokuwiki.org -- a site I've been visiting without issue for months -- using 3 different devices and none of them could reach that site using my home Verizon FIOS connection, but all of them could reach that site if I used another network (i.e., took them to work, use a public WiFi spot, VPN to another network, anything but my home Verizon FIOS network). 

Now, 3 days later, I can reach www.dokuwiki.org just fine with all 3 devices over my Verizon FIOS connection -- and no changes to anything. 

Not sure what it was, but it's unlikely this problem a) suddenly appeared, and then (b) suddenly disappeared for no reason at all. Since there were no changes to anything on my end, I'm pretty sure Verizon found and fixed a configuration issue. 

In any case, over and out.

Can you ping the website?

Or do a traceroute to it?

As requested...a ping and tracert from my FIOS connection to www.dokuwiki.org

Again, thank you very much for helping me with this.

So it looks as though there is not a network issue accessing the site.

I clicked on the URL on your original post and the screen pops right up.

Not sure why it isn't working for you, but at least in my area (Maryland) I don't have any issues accessing the site.

>> So it looks as though there is not a network issue accessing the site. <<

Not really. If you look at the tracert, there's two spots that time out, and the tracert command took about 2 minutes to run...way, way longer than it should. 

Given that, it shouldn't be surprising that my attempts to access the site time out. 

And the critical part is none of this happens if I VPN from the same spot in VA to a server located in NYC, and then access the site. It pops right up. 

I believe there's something wrong with the Verizion FIOS routing to this site.

Timeouts are not uncommon on trade routes.

a lot of devices in the core of networks are set to not respond.

I'll bet if you trace route to other sites, you will also see timeouts.

the fact that you can ping the website and trace route to it proves no network routing issues.

can't explain why VPN works and not direct. Like I said, it works fine for me.

have you tried clearing browser cache?
