Maybe related, maybe not. I was having internet related problems with my mail hosting company this morning. Their entry vanished from DNS records, so they appeared to be non-existant. There have also been some attacks against DNS servers this week. Perhaps this is what you are seeing. My problems with my mail host are gone now, but their customer support line did verify that they were getting a high level of calls similar to my complaint. My connections to eBay have been working fine today.
