    Re: Very slow access

    The site has been borderline unusable numerous times throughout the past 2 or 3 days.

    Re: Very slow access

    Today I've have had several 504 Gateway time outs - both with this site and sister sites (eg codeguru).

    And when not getting 504s, access is very s...l...o...w...

    Re: Very slow access

    Had another 504 today after 'Mark Forums Read' action. When tried to re-display the forum, the forums had been marked as read so the command was received so the issue is probably in displaying the forum.

    Re: Very slow access

    Thank you for the reports.... Wondering if we should add all the "It's back to normal now" reports? It only stands to reason that the info would be helpful. (almost kidding)

    As everyone knows or should know, Intermittent issues like we've been experiencing are hard to diagnose. There is no logical reason why ALL Eleven sites run like a champ one minute and then BOOM... they are slower than heck..... And then back.....

    Today/this morning - all the sites were/are at their best... WHY?

    One area I've been keeping an eye on is at the bottom of the page were we see:

    Currently Active Users - VBF
    There are currently 1,299 users online. 13 members and 1286 guests
    Most users ever online was 26,752, Dec 20th, 2022 at 10:25 PM.

    One of the sister sites: VirtD
    There are currently 4,498 users online. 1 members and 4497 guests
    Most users ever online was 27,057, June 20th, 2024 at 01:08 PM.

    I think the highest number of users has been in the 75k range.... That's a lot of BOTS crawling a site.... BUT - the large numbers don't appear to have any affect. I would think it would.

    Any thoughts on this?

    Re: Very slow access

    From my experience but I'm not a network engineer, those things are mostly handled from your net provider primarily,you can of course put a firewall in after the provider to safe things up but I would first get in touch with them. Also you can start blocking IP's , for us it's easy as we certainly can block Chinese that we get the most attacks from but here we have at least on member so I wouldn't go on that. Also it depends on what the bots are doing, 1300 bots wouldn't be that much if they are just browsing actually. We made a simulation recently for 10.000-20.000 users and we where at 75-80% capacity. Ahh yes also if double a hardware upgrade.
    My 2 cents.

    Working Great today (6/23/2024).

    I put my money on the internet provider. System Upgrades or Excess traffic most likely the cause.
    Besides that, all it takes is someone to hit a telephone pole, or pull a wrong wire!

    It is extremely slow now. Many times it responds with error 503 (Timeout).

    Any chance to move the hosting to a better server?

    This issue is getting really annoying.

    Re: Very slow access

    Thinking left field, is it anything to do with the network path(s) taken? I'm not a network expert but believe that paths can vary from source to destination - even for adjacent packets. ??????? This might explain the 'random' issues seen.

    Re: Very slow access

    It is clearly the cheap hosting.
    Yes, now it is working normal, but it is failing half of the time lately.
    I'm quite sure that it has nothing to do with the country you are from.

    Re: Very slow access

    Guys, we are talking about text pages. Today's connections handle 50 Mbs/s to 1 Gb/s to deliver 4K videos in live streams. Latencies are in general of a few milliseconds.

    And we are waiting like 15 seconds for a server to respond to a petition just to deliver a "504 Time out" page? Explain to me how on earth that could have anything to do with anything else but the server itself.

    Re: Very slow access

    Numerous timeouts today, both just now, and earlier in the day when I was browsing. Basically unusable.

    Just to browse to this thread, log in, and make this post, I got 7 or 8 503 and 504 timeout messages.

    Re: Very slow access

    As mentioned before - ALL of the 50x Errors show up in Log Files on the Server(s).... I believe the IT Guy(s) get a notification....

    I'll see if I can get any feedback from the IT Guys.

    Re: Very slow access

    At this point I get 50/50 503 errors. Meaning a can view a page or get the error at 50% each. Yesterday (all my troubles seemed so far away) I probably got it at 10% ratio.

    LOL, I got the error when posting the issue :P (it passed in the thread but I got the error)

    Re: Very slow access

    Yep, 503/504 back today.

    Everytime the site doesn't respond immediatly, i see a "transferring Data from b.6sc.com" (German Firefox, translating on the fly here) in the bottom left corner of Firefox,
    sometimes staying still for over 10 seconds.

    Then it's a coinflip if i get 503 or 504, or if the request pulls through

    It's not a simple text page coming from a single source. A single page load in VBF will likely include a variety of ads from a variety of sources, and probably a Google auction for the ad space. Any of those steps could be causing trouble. Zvoni tends to see one particular location, others see other locations.

    Do you mean that the "locations" are fetched from the server side? Because if they are in the client side, I mean the browser, the server should respond with the main page and the browser get all the other pages and files.
    But the server does not respond for a while, and when it does, it respond when an error page (in the cases it does those errors), so... what you say only makes sense to my understanding if those web pages are fetched by the server prior to deliver the page, otherwise what we see should be something different.

    In other words: those pages that we see, the ones that say "504 Gateway Time-Out" and "Error 503 first byte timeout" are generated by the server, not locally on the browser. So the issues are at the server side.

    Maybe the server needs to get some texts for ads from other servers before combining them and making the final page, and one of those servers are taking too long. Or something like that. In that case I think that someone could disconnect one by one in the time the forum is failing and see which one ad is causing the issue.

    Re: Very slow access

    Whilst I sometimes get the slowdowns when using the sister site codeguru.com, I've never had any 503/504 errors using that site - but it's user activity is much less then this site.

    Also for me 503/504 issues occur when a page is to be displayed - not when info is sent. So if I post, the post is accepted and then a 503/504 error occurs. Or if I use Mark Forms Read, the action will be undertaken but I might get a 503/504 on the re-display.

    Re: Very slow access

    Especially slow at the moment, seems to happen more on first access rather than subsequent tries. Is it possible that any site cacheing has filled up the local store preventing subsequent cache accesses, so it has to resolve the request by fetching and building a real copy of the page. It initially tries to access the cache and simply fails. Fulfilling all the resulting 'real' page requests might in addition put an unexpected load on the server. Check the space usage where the cache is maintained and refresh the cache. There may be more than one cache, a server cache and an application 'hard' cache where full pages are written.

    I have also noticed that one of my browsers has been served some content it really does not like through Vbforums, handling it badly and causing the browser to crash. That has only happened recently and is not a normal situation, the browser I am using is normally very robust. It felt as if the serving of adverts was the delay and in that delay it was serving up something unexpected.

    Re: Very slow access

    It may just be coincidence, but the slow response seems to have started about the same time as 4 new external scripts were added. How can I tell? I use NoScript with FireFox, where scripts are subjected to default analysis unless otherwise defined. About 3 days ago, 3 scripts produced NoScript symbols on every forum access, but not the individual threads. When I changed the settings to UNTRUSTED, the NoScipt symbols disappeared. The scripts that I currently have disabled are:
    6sc.co
    *6sense.com
    doubleclick.net
    *jsdelivr.net
    ml314.com
    *ntv.io
    quantcast.com
    quantserve.com
    *technologyadvice.com
    zi-scripts.com
    The ones starting with an asterisk I believe are the new ones I set to UNTRUSTED (if I can trust my own memory).
