Contabo VPS severe performance issue returned after migration (disk I/O related?)
I’ve been running a Contabo VPS for 2+ years and haven’t had issues like this before, so I wanted to check if others are seeing something similar recently.
Over the last couple days I’ve experienced:
- Minecraft server dropping from stable 20 TPS down to ~6–14 TPS under no load
- SSH becoming noticeably delayed
- Slow service startup times
- General system-wide sluggishness
I checked disk performance with iostat and saw write latency (w_await) consistently in the 100–500ms range, which is far beyond normal SSD behavior.
I opened a support ticket and my VPS was migrated to a different host.
After migration:
- Performance immediately returned to normal but honestly not quite as good as it was about a week ago- (~20 TPS, no lag)
However, shortly after (about a day later i checked back again):
- The same degradation returned (~15 TPS under no load)
- Similar symptoms reappeared
So the pattern is:
- Severe degradation
- Migration fixes it
- Issue returns again
Given this, it doesn’t seem consistent with typical “noisy neighbor” behavior, especially with the disk latency observed and the temporary recovery after migration.
I also noticed there are ongoing security-related updates and backup system issues on the status page, so I’m wondering if there could be broader infrastructure impact.
Has anyone else experienced similar VPS performance issues in the last few days?
Trying to determine whether this is isolated or part of a wider issue.
