I’ve been receiving emails from my website host, Vice Temple, every day for a week with this message. Usually the number of connections that have been refused is low but sometimes it’s as many as 100-200. These reports each cover 12-hour periods. I’ve received a few of these in the past but very sporadically.
My current limit is 20 and I’m considering upgrading my service to 40 concurrent connections. But since this is a strictly free, hobbyist blog I’m not sure it’s worth it. If someone can’t connect then they can just try again later.
