Low speeds at night--host specific??

Discussion created by jagerx9 on Jan 13, 2019

Every night, something very interesting happens. Some host servers are much slower than others.

Interestingly, running speed tests from various sites yields different results. On an Internet 600 plan:
- Ookla Speedtest: 600mbps

- Fast.com (Netflix): 320mbps

- Google Speedtest: 130mbps

- CIRA: 2mbps (yes)

 

Anyone else noticing this? Twitch is unwatchable with constant buffering, for example. Nothing at all on my end has changed and everything's been purged and reset. Something is not quite right.. maybe an issue with a node?

 

Here is the data from the CIRA test.
