    I started getting repeated 522 errors connecting to the ECF server in the last 15 minutes. Anyone else?

    Is anyone watching this Classy? Are we some times getting to big for the ECF server britches - so to speak - if/when too many members are trying to access at the same time? Seems to be a random, but recurring, kind of problem.

    It's related to our CDN static content distribution system and cross-domain requests handling, which is a way of distributing visitor requests for certain non-changing ECF content plus content supplied by others, without lags caused by network issues. In theory, anyway...

    Because of a combination of vBulletin software code errors and implementation issues, it does not work faultlessly. For some people in some locations, there is a temporary network crash that means pages won't load without the locally-provided content. This is primarily a forum software error because the page requested should load the ECF content regardless of whatever else is requested; there is also a CDN error in order to cause the issue to arise in the first place.

    So it's a chain error caused by at least two faults and only affects certain visitors occasionally. To fix it we'd need to move to more modern forum software (vBulletin is no longer properly maintained), and double our server cluster size so that all content can be hosted locally. It's a possibility, but not a priority, because the current system works OK for 99.99% of people, 99.99% of the time.

    I'll find out if it would be of any use to map the fail locations / times so we can ask the CDN contractor for a fix. That's a possibility.

    Thank Roly. It's not a big deal, it's just become a recurring, albeit infrequent, thing - that's what made me wonder what was going on. We (you) don't know some times if hiccups represent a big thing or a little thing unless they are brought forward.

    Yep that's OK, we do need to know if there's a problem anywhere.

    The router congestion issues that some providers are having are most likely part of the cause.

    I just got a run of three errors in a row:

    Error 524 Ray ID: 16065e6390bc040c
    A timeout occurred

    Then the next two reload attempts produced:

    Database error

    Error 524 Ray ID: 160663f03238040c
    A timeout occurred

    Seems to be choking in the last half hour. Page loads keep coming up with "database error" with an ECF logo (I think it's an ECF logo) and nothing else. After about three "database errors" I get this:

    Website is offline

    No cached version of this page is available.
    Error 502 Ray ID: 1781bbb580ce01ef
    Bad gateway

    I broke ECF! :facepalm:

    Maybe it was all the spammers registering at the same time, so that could all have a go at our poor New Members forum. :(
