OK, it doesn't get any weirder than this.
My home network has quite a few computers on it. A Cablevision Motorola cable modem, attached to a Linksys router which has a few computers attached to it as well as a Linksys 8-Port workgroup switch (hub) in my office, which also has a few computers attached to it. Most of the machines run Fedora 13, although I keep one Windows 7 box attached for experimenting. OK.
One of the computers running Fedora 13 is dedicated as a print server and a 24/7 IRC box which runs Konversatiion. Over the past 2 weeks I have noticed something strange. Everytime I go to the Amazon website and either try to log on, or, search the site, oftc, freenode and now linuxdotcom disconnect. It's been a couple of weeks because I couldn't believe this was happening. I've had this IRC box running 24/7 for a couple of years and have visited Amazon any number of times and this has never happened before.
I can try using Firefox or Chrome. I can try on any of the Linux boxes and today I decided to try on the Windows box with the same result, IRC channels get disconnected. I can try to access using bookmarks, or googling Amazon and entering that way, same result.
I've tried restarting the modem, router and hub. I've checked DNS. I've tried accessing all sorts of other websites, pinging them, searching on them and Amazon is the only one that knocks out my IRC.
I've looked over my router settings and didn't find any clues, but, I'm not nearly proficient enough with networking to know where to look next.
BTW - I can disconnect oftc/freenode and then reconnect again without restarting any hardware, I finally figured this out today. I'm just so puzzled, why would accessing only Amazon cut off Konversation's access to the IRC servers?
Does anyone have any ideas?
Thanks in Advance
