Yikes... my site has been acting strangely or totally down since the evening of 2/10/2006 until this evening

At first I'm pretty nervous because I suddenly remembered that I haven't pay the bill and it's going to due... in 1 day time....
However, the sql is acting strange and keep throwing a "Too many connections" error on my face. If I didn't pay the bill, they should stop serving my site temporarily and shouldn't be this weird or stupid. After checking out with the admin, I just realized they're carrying out a server update. In fact, it's a huge update... .
The RAM has arrived at the datacentre and they have advised an upgrade window of approximately four (4) hours. The upgrade will only take a few minutes, but please allow the full window so as to allow time for any issues that may arise. We expect full services to be restored by approximately 14:30 AEST.
...
We are waiting for a response from the data centre about an upgrade due to a RAM issue on the Milkyway server, the server is currently running on a gigabyte of RAM thus using quite abit of swap causing the slow accessing times. The main services suffering are - ftp, email and sql. We appologise for the inconvinience.
So, during the update process in these few days, sometimes the site is totally down, sometimes it's up but the PHP script has sql connection problem. If I managed to get through, either everything is fine or I'll notice the site's content is old one. It's sort of a database rollback, just that the problem is it didn't rollback to the most recents one. It's like right now I'm seeing the most updated content on my site, 1 hr later I visit again it's rollback to the content that's few days back. Then I come back again, it's restored to the latest one... I can't issue a lockdown on my site because of this and also FTP is not working too...
Anyway, thank god the update has completed, and thank god again all the data is restored properly
