Site broke down every weekend? - Electronic Circuits Projects Diagrams Free

Why is this site broken every Saturday? And all day some other days too? The uptime isn't great, it seems like.

all day today it was down to, i thought it may have been a local server problem, but obviously not.

The database seems to be going down quite a bit recently, if the error message is to be believed. Maybe there's a new server in use which isn't configured to handle the load yet, or which just plain can't deal with the load.

It could be something else too. The other day I could visit the main page (the forum list) just fine, but trying to visit any forum, thread, or post resulted in a database error message.

I'm sure they'll work it out.

They seem to fix it pretty quickly.

I wonder what the problem is.

I was freaking out because I needed this website. Without it I don't Know how I am going to waste time!

Hero999 · 3rd February 2008, 09:11 PM

I often feel like that too.

I agree. This is the only piece of sanity i get in a day!

HarveyH42 · 3rd February 2008, 09:42 PM

I'm sure there is still a lot of details to work out from the recent move. Just be patient, maybe start a new project when the site is down, take lots of pictures, and post the results when it comes back up...

I chat on other forums that show thousands of people online at the same time without problems.
But the server for this site runs away whenever there are more than 20 people online. Or the server just goes to sleep for a few hours.

We understand that this site does get a bit of downtime, not quite every weekend, but every now and then. We are however always trying to improve this, recently we upgraded the server to help out (about a month back).

One of the main reasons for downtime is rouge bots that hammer our site. What they do is try and download pages or the entire site for their own purposes (search engine caches, spam databases, content leeches, offline copies, etc) and they do this without consideration to the load that it puts on the server, they use as many connections and download as many pages as fast as possible. Obviously search engines like google, yahoo, msn don’t do this but there are many others out there that do and that is the problem we face on a daily basis.

Another issue is the constant growth this site has experienced in the past. Look at the stats at the bottom of the page and you will see we hit over 200,000 unique visitors in the last month. That’s an incredible amount of electronic hobbyist!!

I am sure that supporting this site both physically and financially can get old.

Let me take the time to thank you for that.

I feel your pain. At work we regularly get hit by kiddie bots which keep looking for phpMyAdmin and other stuff. We don't have particularly public sites (niche market) but some of the script kiddies aren't smart/courteous enough to turn down the retry time and we just get nuked.

You guys do a fantastic job with the popularity the site has gotten.

I am amazed at the stat's.
Right now there are 45 members and a whopping 550 guests. And the server is doing fine.

Marks256 · 11th February 2008, 09:49 PM

I agree with 3v0. Thanks for the great site, electromaster!

Hero999 · 15th February 2008, 02:29 PM

It's amazing that you manage to do this without big huge annoying adverts, unlike Electronics Lab.

Also, I take it that this is why you don't allow guests access to attachements.
