Just for fun this morning we reviewed Wikidot.com's uptime statistics over the last months. After fixing caching issues this summer, and before upgrading to the new super-fast database servers, we had about 99.7% uptime, and since then it's around 99.85%.
This comes down to about 1 hour downtime per month, which is caused by specific failures in different parts of the Wikidot cluster: usually due to extreme load peaks.
We're aiming for higher uptime (99.99% or under 5 minutes per month would be nice), in two ways. First, to improve the way we respond to problems, to detect them earlier and recover faster (and without service interruption). Second, to continue work on replication and caching so that your Wikidot.com sites have failsafe backups, both static HTML and live Wikidot.
I am really happy with Wikidot's current uptime.
It is more reliable than most other FREE web hosting providers :-)

woot!! go wikidot!
When are peak times? What causes wikidot to go down?
Peak times are during the US working day.
Very little, now :-)

These are good figures although it doesn't really surprise me. The underlying infrastructure of Wikidot has always seemed to be good and, odd things like Snow Leopard apart, the uptime has never really been an issue. I was reading an article a while back on the astonomical cost of getting to 5"9s", i.e 99.99999% - millions! So 2 "9s" is probably a more realistic target to shoot at. Well done.

Today I also checked out Google's new Site Performance tool, and:
This, as I believe, comes form their crawling statistics.
We are also reaching top 3,000 internet sites according to Alexa, or top 2,000 sites according Quantcast.
So not bad IMHO ;-)

Check out what wolframAlpha says.
Traffic doubled since January… from 300,000 visitors per day to 600,000 per day. :-)

(Note that Wolfram Alpha tends to live in the domain of imaginary numbers. The actual daily visitors is nowhere as high as this.)

Where is Tuesday Rant XX ?

Great uptime! Same as tsangk, I've never really experienced many issues with Wikidot. That may be because we're on the other side of the world to the US, but I think anyone can be happy with just an hour downtime per month.
A minute? I'm not complaining :) That'd be great.

The actual downtime per month comes from very short unavailability periods, a minute or two per day, sometimes even less (but such periods are rounded up to full minutes). So even if a monitoring service cannot cannot access pages for a few seconds, full minute is accounted.
As Pieter says, we are gradually building more and more stable, reliable infrastructure for Wikidot. It is important for both our paid and free users — nobody likes to see "site down", either this is a business site, collaboration wiki or a personal blog.
