I was helping someone debug their computer network this morning. While testing, I found some of my web sites (for example: KirkLindstrom.com) hosted by GoDaddy.com worked and some did not. My web pages hosted on other sites worked just fine.
I tried their web site and even sent a support message. Their own home page said there were no issues... Yet I've learned they tweeted they had issues several hours before I checked!
It is really tough to debug a network problem when the internet itself is having issues. What a waste of time running around trying to fix things that were not my problem and I've paid good money for reliability!!!
