As soon as I posted the good news from my last announcement. I left the office, went home and checked the server. Instagram has literally released a new update and its causing some delays in arrival times on likes.
We are uncertain this was caused by yesterdays outage, we are investigating the issue. What doesn't help is now we are on peak times which equates to naturally slower arrival times. Don't worry, we are investigating the issues and trying to decide if its a problem with Instagram servers or an actual algorithm update.
You can still post, but the likes will be delayed. So if you have an important or sponsored post, I would recommend to delay it.
The developers are working the night shift and I'll update you shortly regarding this. But on't worry, it doesn't seem like anything drastic.
