Being a fairly knowledgeable network person, I spent hours trying to diagnose the problem. I could get to all other web sites, but not to anything in the plaxo.com domain. Worse, I could resolve, ping and traceroute looked fine.
First I thought it might be something caused by Plaxo being bought by Comcast. Comcast had just recently been in the news for blocking traffic to keep bandwidth available, so I figured it wasn’t inconceivable that somebody made a mistake in a firewall somewhere that was blocking traffic between them and AT&T.
I sent an email to Plaxo to ask them if their site was up, and called AT&T to see if we could diagnose the problem. AT&T as usual was very nice (and annoying) and started me out with the normal insane steps:
- Turn off your firewall
- Clear your cache
- Turn off your router
After getting past all the annoying stuff, I got to their level 2 support, and then to the 2Wire support to see if they could find anything with my router that might be causing this. Naturally they found nothing, and everything looked OK.
So I escalated with Plaxo, calling them on the phone to see if there was anything they could do. There were emails and phone calls back in forth that never solved the problem:
- First call I was told that there was a problem with one of their servers, and that it would be working the next day (not).
- Another call I was told they had found the problem in their web server, and it would be fixed shortly
- I got numerous emails telling me to uninstall the Plaxo software and log in again, which of course didn’t work since I couldn’t even get to the web site.
- I had numerous emails diagnosing the problem as a Mac issue, or a PC issue, which again it wasn’t since it was happening on the Mac, iPhone and PC (and the iPhone doesn’t even have a Plaxo client).
Finally at some point, I got a support guy who told me that my IP address was indeed blocked at their server. Now we’re getting somewhere. But no, it still doesn’t work.
Luckily for me this guy is good, so he tells me that there was an old version of the Plaxo client for Mac that their servers were detecting as a bot attack, so if I uninstall that everything should be golden. I do, and lo and behold I can get to Plaxo again …
So it appears that Plaxo can be incompatible with itself …
I wonder how many people are blocked with the same problem right now.
