Thank you for letting us know, @TheRealGeneralInfo, we're passing along this information to me looked at.

By any chance, could you clarify the time zone you're in - to help pinpoint the timing?

Thanks!

Those are CDN-generated messages.  They could be for a variety of reasons.  These problems went away by itself?

@ATTCommunityTeam, time zone seems to be EST.

@JefferMC, (a) what might "CDN" stand for, (b) what might CDN's purpose be, and (c) might you be aware of documentation that lists the potential causes for the generated messages?

Re: "These problems went away by itself", I seem to have been able to log into AT&T Community Forums without display of similar messages.

CDN = Content Delivery Network.  Examples include Akamai and Cloudflare.

A CDN is a service provided to a website owner to speed the delivery of content to the end users and reducing the load on the website's own servers, while also providing some security and other access restrictions.  Requests for a web address get routed through the CDN where they can be studied before forwarding them on to the actual site, or responding with content the CDN has cached from a previous request for that content.

The CDN provides categories of things on which it can base a decision to block traffic.  The website owner can choose from that list what he wants to have implemented.  These things include:  IP ranges from block lists, IP Geolocation (i.e. in or outside of a country), HTTP header size (number of cookies, etc.), time of day, load (too many requests) and can be varied by URL host and/or path.

When you get such a message, the reference ID identifies your particular request.  The website owner can request of the CDN the rule that blocked the request (i.e. why), but only the website owner can do that.  And, as a rule, users are unable to get to anyone at a website owner to make that request of the CDN.

You're in EST?  What part of the country doesn't shift to EDT in March?

@JefferMC: I express gratitude for the CDN-related information.

Re: EST vs EDT, out of curiosity, might you have considered "the right-most time zone in the continental United States" to have been an appropriate generic answer to the time zone question?
