I am on Vultr shared plan, US-East. For 72 hours my WordPress site returns intermittent 502 Bad Gateway. Support claims "no issues on their end."
My monitoring shows CPU steal time spiking to 45% during peak hours. IONice values suggest another tenant is monopolizing disk I/O. The server has 32 cores per cPanel license but I count 847 hosting accounts on this node via reverse DNS enumeration.
Hot take: this is classic overselling. For what it's worth, I have documented everything. I am prepared to migrate but want to confirm my diagnosis before naming names publicly. Has anyone else seen this pattern on Vultr recently? I can share Grafana screenshots if useful.
