A few minutes after the update is complete I can access my site again. You actually take down the VPS that is running my site only with 4GB ram and 2 CPU's. And I have written about this before. I thought you fixed it. Seems not the case. The site cannot be viewed when an update is happening. And I only have about 50 products. Imagine if I had a 100. Are you indexing the tables that you are updating against? Are you using likes? If so that does table scans. I am a developer by trade and build a ton of db apps at scale. If I could read your code I would help you out, but you have it obfuscated.
