Yes, it has gotten very slow a few times this week. It's not the database (that'd give a timeout and I ran checks on it the other night), so I can only assume it's on the web tier, but I've no idea where exactly. I'll put a query into the hosts to see if I can get some metrics.
With all the media exposure recently, there was a definite spike of activity yesterday.
Excluding the 30th, the average traffic for March was
5,619 Page Views/Day
719 Visits/Day
The 30th had
12,167 Page Views
1,167 Visits
I don't have statistics on today yet, but clearly a huge spike probably based on the IT article. We have had similar spikes in the past, most notably 20/01/2009 and 02/02/2009 with similar numbers. Can't recall what might have sparked them though.
Oh, and Thom's poll...
I started looking into new hosting about 6 months ago, but the slowness we had then went away. I may have to reconsider options depending on what I find out in the back end. Oh matron!
