Yep - lets see how it pans out. I really hope for your sake that you can get connected today. Please do let us know as soon as you are ...
I look at scenarios like yours to kinda gauge how my experience will go, but seeing as I'm with a different FNO, it might be completely different to yours.
Honestly, I think many, many more people than are represented / voiced in this thread took advantage of this deal. And I think the large majority of them would have waited for the 1st to switch over to take advantage of a full first free month. So I'm guessing Openserve etc. had more simultaneous migrations than they've ever had to deal with, and there was a queue / backlog. Judging from the general slowdown / unavailability of support on AH's channels yesterday, it seems they had a ton of support queries to deal with too. (Live chat was completely offline at one point, Whatsapp took a while, 20 min backlog on phone support, etc)
So I think quite a few of these migration / installation frustrations are down to volume and (I'm hoping) not indicative of ongoing future support.
