OK this is embarrassing... I am unable to access WebmasterWorld.com from any browser or PC on my LAN. It was OK yesterday. I don't have a problem accessing any other website that I am aware of. I've tried changing DNS servers. Rebooted router / assigned new external IP address (I was expecting this to fix it / unblock me, but it didnt.). Cleared browser cache and cookies, tried browser privacy mode.
I am currently accessing this on my phone / mobile network, which is OK (but awkward). I can also access the site OK via a proxy.
Bunch of downtime on backbone today. There is widespread regional outages. This is related to an unannounced maintenance on some of the nationwide routing infrastructure in Cogent, Layer3, and Comcast.
I saw an announcement yesterday at the NOAA Satellite server site that there would be a routine running for 8 hours minimum today starting at 8:30 AM EDT testing infrastructure. I didn't go read the whole thing but I sort of expect to see possible issues as a result.
So, it's not just me then? Although it does feel a lot like it is. I've tried several of those site check tools... Ismywebsiteupnow.com, pingdom, etc. and they all report success - even for servers that appear to be down the road from me?! Except my requests to WebmasterWorld just time out still.
