My VPS was migrated to new servers several weeks ago and my IP addresses changed. I have had a series of down times over the last several weeks, most of which have been related to finding yet another spot where I did not change the IP addresses to the new ones and caused some sort of instability. Having thought I had gotten them all, I found yesterday that I had not properly updated my records at Incapsula, a filtering and caching service I use for this blog and a few others. Now that is fixed. Hopefully, that is the end of it.
