UPDATE: My logs from the following night didn't have any of the entries detailed in my post below. I don't think this is actually a Mercurius issue, but was rather a connectivity problem happening on stats.minecraftforge.net.

I'm not sure if I can mark this issue resolved or not, but I consider it to be so.

Original Post:

My logs recently filled up with a bunch of spam from Mercurius having a problem reaching stats.minecraftforge.net/api/v2/. Probably an issue with the MinecraftForge site, but posting here in case there's something else going on.
