Well I think they should send people here not just put useless annoucement there.
he Community will be undergoing maintenance from Friday February 21 - Friday, February 28 and will be “read only” during this time. To learn more, check out our Announcements blog post.
For almost like 2-3 weeks Airtable forums are inaccessible. This is ridiculous what they are doing. Incompetent. So if they move to a new platform, which is unsurprising, they should make a backup copy of the old one and leave it read-only.
If you looking for old information, the old Airtable forums are still accessible via the Internet Archive site:
Worst part is when you google to try to solve an Airtable problem, and the results are all community forums, and you can’t load them 
It is understandable that one gets annoyed due to the loss of this resource. But a little compassion and patience are in order here. It cannot be easy to do all they are doing and still change out a help system. I agree that they should have planned to have a read only copy available for research. But I know that I cannot produce the product they produce. I use it every day and I am in awe of what they have accomplished. I am sure that there are things that can be improved and I have a long lists of wants. But all in all, if you spent your life using MS Access, you would thank your lucky stars that Airtable exists. As I said, this world could use a littel more compassion. Best, Scott
