Aware of all the slowness. To be honest, we have spent the last several days and countless hours planning the upgrades. Unfortunately, we couldn't cover all eventualities. First we had a DNS issue which is very rare occurrence. Now we have PHP which keeps on hanging which is directly connected to this forum. Luckily other critical services are working as normal. So, that's the good side of it.
Once I am confident about the server being stable, I would really appreciate if everyone could help me test. Thank you for all the patience. Hopefully not too long now.
