Without seeing your config file or anything like that, there's no possible way we can help you to know if there's a config issue or something else going on.
That being said.. I wonder if they are doing work on this end to facilitate upgrades for SERVS. I originally only had 14B Ashland in my feed because there was no way to filter by NAC and keep WVSIRN out of the feed.. but I AI-coded NAC aliasing into SDRTrunk and re-added a bunch of 14, 8, and 9 towers, and I feel like there's more traffic now. So maybe there's some simulcast links down right now, or it's just that... slow.
