Server Error Reports

[tautech]

Just an update on the above..

We are fully operational on two servers again and have been for a little bit now.

A day, a week or a month ?
Yet it seems we still have some issues with server overloads ....at least at my end when connection fails.

What to the logs look like ?

[RoGeorge]

That's great, thank you! 

May I kindly ask if we can have a preview that renders math formulas (at preview time, before pressing Post).  Right now the preview does not render the graphic form for math formulas.  I can see the drawn equations only after pressing Post, which is cumbersome when there is more complicated formulas to write.

Example:

Code: [Select]

Write a line of text with the inline formula \$ a = b + c \$, or a formula in display mode (aka single line centered formula)\[ x = y + z \] The formulas will only appear rendered in their graphical form only after posting the message, but not at preview.
Write a line of text with the inline formula \$ a = b + c \$, or a formula in display mode (aka single line centered formula)\[ x = y + z \] The formulas will only appear rendered in their graphical form only after posting the message, but not at preview.

This is not a critical bug, but rather a nice to have, and only if it doesn't mess anything else.



For now (if that helps debugging) I've found a workaround:
- press Reply to get to the edit post page
- save the Reply page on disk (from the web browser, mine is Firefox ESR)
- click to open in another browser tab the saved page from the local disk
- edit the reply text and the formula in the tab that was opened from the local disk
- press Preview in the tab opened from the local disk, this will show a "live" preview coming from EEVblog, a preview with the formulas rendered   
- at another press of the preview (from the "live" page), the formulas will not be rendered
- now, if I want to make further edits, I press "back" in the browser, so to arrive again at the reply page that was opened from local disk, edit and press preview again, that will open again a preview coming from the EEVblog (including rendered formulas) and so on
- once the reply text and all formulas are OK in the reply tab that was opened from the local disk, press "Post".

About a week now of stable uptime.
Servers are monitored 24x7 for overload scenarios and we are not even close.
Connection failures are not server overload issues, more likely a routing issue to the server.

Off topic, this is "Server Error Reports"

[RoGeorge]

True that, but they are all servers, the hosting/hardware server, the database server that keeps all the messages, the web server serving the SMF pages, etc.   

Is there any SMF Plugins Error Reports thread, or feature request thread?

[YetAnotherTechie]

Have you seen: https://www.eevblog.com/forum/news/news-forum-reverted-to-backup/125/ ?
I still don't get anything from eevblog on my hotmail account.

I'd like to point out that notifications started showing up again in my hotmail account, beggining in 14 of August.

You're asking for a feature in a server error reporting thread that is dedicated to this purpose. This thread is special as it alerts me when posted that there might be a server fault I need to investigate.
I suggest you open a new thread asking for such a feature if you desire it, I don't manage the plugins/features on this forum.

Good to hear, this was resolved when Gorilla Servers finally brought up our private network again and we were able to route the email through our mail gateways correctly.

Starting this morning, sometimes the pages does not load even after waiting for 30 seconds or so (I'm using mostly the two links in the upper left corner near the avatar, Firefox ESR, Kubuntu).  If I wait for a while then try clicking again, it works.  On my side it seems to be happening with EEVblog only, other websites are responsive.

Anybody else seeing random page loading failures today?

[PlainName]

I keep getting just the plain text for a page, but a refresh usually gets me the proper thing. Doesn't happen too often, and it's been like this for the past couple of days.

[gnif]

Thanks guys, I will have a dig into it.

[PA0PBZ]

I noticed that yesterday the .css failed to load, but it just happened once and a refresh solved it.

[MrMobodies]

I am am not sure if it is a server error or not but just noticed a whole load of forum boards/categories all suddenly disappeared.

EEVBlog specific (disappeared):
EEVdiscover, EEVBlab, Suggestions

Off Topic Hobbies (nothing underneath):
Mechanical Engineering.
3D printing
Cooking

On Dec 20th 2021, at around 8:27 PM (UTC and UK time), the Forum server disappeared, completely (including downforjustme or everyone types of tests), for around 5 minutes or so.

(I did not note the exact time, so could be out by a few minutes).

Eevblog.com Status
Is eevblog.com down right now?
It's not just you! eevblog.com is down.

[RoGeorge]

Can confirm that, too, but it was only for a very short time.
Probably just a minor version bump that required a server restart...

There was no outage on our end during that period. More likely a down route between you an the server as we were processing requests throughout the reported period without interruption (see attached)

[PlainName]

I can see the problem. Your local time is "24 January 2022, 20:39:06" and the chart is "2022-01-25-064231".

Wow. So, because myself, RoGeorge and (presumably) the DownForEveryOne IP checker, perhaps used a common European or other internet route. We all had difficulties getting to EEVblog.com.
That makes sense, as other people who were unaffected, wouldn't know their's was working while ours wasn't. So they wouldn't have reported that it was working at that time, just assumed they weren't using it at that time.
Thanks for results. It didn't occur to me, that multiple people (using the same massive internet routes), could have problems, nothing to do with EEVblog.

The date, shown in the bottom left hand corner, of the image Gnif has posted, seems to be 20th December 2021, which corresponds to the date of my report.

[PlainName]

Ah. Old eyes, here.

[gnif]

Yeah, the filename date is just due to the tool I used to take a screenshot, the range covered is 2021-12-20 to 2021-12-21

[MrMobodies]

Sorry I am not sure if it is an error but I was looking in the Supporters lounge and noticed this thread that remembered I couldn't find for a while suddenly appearing in there:

Gender politics has now infected engineering as well.
https://www.eevblog.com/forum/supporters-lounge/gender-politics-has-now-infected-engineering-as-well/1800/

I wonder what happened, was it moved by mistake or were there lots of complaints about it?

[gnif]

This is server error reports, it might have been moved by a mod, or dave... either way this is not the place to ask. This thread is special and alerts me when people post to it, it's for outages/crashes, it's not for moved posts, etc.

[MrMobodies]

I am sorry about that, gnif, I forgot and just remembered that was for the Moderation thread (use to be sticky here) that also seems to have gone somewhere.

Used to be here as a sticky but now unstuck and the only one now not locked.

Just FYI, since the last 10 hours or so, I can not access eevblog.com from Bucharest/Romania/EU.

However, the "is it down" type of websites show eevblog up all around the world but when I try to traceroute I get this:

Posted this using Tor browser, so it's using some other route to reach eevblog.  It seems like it's a routing problem on my side, though I've noticed the number of logged users right now (173) is lower than usual.  I suspect a wider area is affected, not just my ISP.  Changing the OS or restarting the router for a new IP doesn't help.
