XRE-03059...Again

Getting XRE-03059 on ESPN, local ABC station, etc. This has happened multiple times since mid-December. Often there's "no outage" and I'm gaslit to believe it's our stuff and then, magically, planned maintenance or an outage pops up and when that's completed everything works again! We haven't had any issues for quite some time (weeks? A month?) until yesterday we noticed it again. Thanks!
