I went to antpool because I bought an antrouter for shits and giggles. I moved the rest of my mining equipment over out of laziness so I would not have to keep an eye on multiple pools. After the repeated downtime and issues with no answers, I hopped all my equipment back to my old pool.
Wise decision to move away from this as primary, I have these as one of my backups. Don't forget to have a backup pool (or more) though ;-)
Antpool luck isn't so good lately past month or so:
