content: I'm going to try a new EEVblog web server with sitecloud.comCould take a few days to process and do a trial transfer, but if you see any hiccups in the next few days, that's likely what's happening. The plan is to change everything over intact, so you won't notice the difference., but we'll see what happens.Twitter will be where I post updates if/when the shit hits the fan!Dave.

content: The old server won't be going down, so it it all goes tits-up I can point the DNS back to Hostmonster and it's business as usual!SiteCloud claim to handle the web site migration for you, so lets see what they can do.The worst that will happen is a few blog comments and forum posts are lost in the few hours it takes to transfer. Although I should really disable the forum and comments until the change is done.Dave.

content: Ok, the deed is done.However there is one quirk I'm interested in if anyone has the technical knowledge to answer it.Usingwww.network-tools.comIf I do a trace on eevblog.com I get plenty of timeouts and it eventually can't finish the trace. This is to my new Sitecloud server.However, if I try the same trace on my old server (hostmonster) using boondaburra.com, there are no timeouts, and completes the trace in 9 hops every time.Pings to either site are fine and very fast, but it's the trace thing that has me concerned.Anyone know exactly what this means and what impact (if any) it might have one using this new server to host EEVbog?i.e. would it impact my search engine ranking or anything else?ThanksDave.

content: It's nothing to worry about - Amazon are blocking the traceroute packets within their network, or their routers are using private address space. If you have shell access to the server it's running on, you could try the trace from that end to see if it's being blocked at the border router or on those machines.I just tried doing a ping with the record route option set and got:gi1-0-0.bdr1.iad1.internode.on.net (206.223.115.197)72.21.197.3572.21.222.144216.182.224.54216.182.224.18216.182.232.66Compare this with the traceroute:8 equinix01-iad2.amazon.com (206.223.115.68) 264.754 ms 265.372 ms 266.058 ms9 72.21.197.40 (72.21.197.40) 264.802 ms 264.833 ms 265.145 ms10 72.21.222.149 (72.21.222.149) 265.643 ms * 265.188 ms11 * * *12 * * *13 * * *14 s1.cloudwelcome.com (184.73.164.210) 265.145 ms 265.384 ms 265.209 msSo it's the 216.182.x.x routers aren't responding to traceroute.

content: Yep, its completely normal. The response is blocked so it is more difficult to map out the inside of of various providers networks. All you are getting when you get IPs are the public facing edges.

content: I would suggest to let this day pass ... with out benchmarks.There is an serious issue today with the main Internet connections , between US and Europe.I have serious issues all day , but when I connect on the current server , my navigation are truly fast ..When I tried to use thewww.network-tools.com, because the service are located in US ,I got one report indicating problems .. and time outs .So, lets forget the benchmarks today ...

content: Hmm, according to my new server, I got these requests for August:QuoteWhat has me worries is the "failed requests", about 8% or so of all accesses.Anyone know what this means and the significance of it?I've asked the provider, but won't hold my breath they will answer.The failed access files are:QuoteWhy so many failed requests for Blog #33 podcast I wonder?Dave.

content: "Failed requests" generally means any request that had a 400 or 500 error code. You'd probably have to look at the logs to see when and why this happened, if it's working at the moment.

content: So I hate to say this, but for at least an hour this morning (California time),I was getting something like:Service UnavailableI'm currently seeing some kind of problem with unread messages. If I clickon "Show unread posts since last visit", I get nothing, but if I just go tothe front page of the forum, some of the forum sections are showing newposts (i.e. the icon is *not* grayed out). And the forum stats show a postingwithin the last hour. Kinda puzzled over this split personality.Scott

content: Well, I tried logging out and back in again, but that hasn't cured the new messages problem.Even weirder, I had to click on logout 3 times, because the first 2 times I got this message:Session verification failed. Please try logging out and back in again, and then try again.[now getting this session verification message on first try to post this message]Think I'll just go to bed and hope things are healed overnight :-)Scott

content: Got the same error myself yesterday : 503I think it has something to do with the load on the server. Can you measure it, Dave, and maybe tell us the results ?At least what does /proc/loadavg says. SHould be something like this :[root@private02 ~]# cat /proc/loadavg0.36 0.45 0.49 2/214 30494I had these problems too on a high-traffic server but mine were mostly because of a floodLE : i keep getting session expired error. I think it has to do with some php.ini modifications you might have made recently.Any php upgrade or something like this ? Check where your session files are stored (should be in /tmp folder or something else with write access for the owner of the php process). Also try to check if there is enough space on the server (sounds like check if it is plugged in but believe me, i have been in a situation like this; paranoid is not enough)

content: Yeah I keep getting random session expired errors. It seems to only happen for certain links.When I hit reply, it works fine. When I hit quote or modify, it doesn't. It seems like any links like:https://www.eevblog.com/forum/index.php?action=post;quote=14642;topic=1134.0;num_replies=8;sesc=ee15cee151e0229983057736494795a0Don't work. Note the sesc field. It isn't there for links that do work.No matter what I do, clear cookies, etc, these links just refuse to work. Unfortunately just removing the field doesn't magically fix it either.

content: I am now on cloud based server (sitecloud.com) specifically to prevent any server load problems!I have contacted them about this and lets see what happens, because I can't figure it out.There is now way I can monitor my "compute cycle" usage, they don't have that facility working yet.Sitecloud.com is looking suckier every day. I should have stuck with Hostmonster.comDave.
