Updates: what GuaBase posted, and what changed here
GuaBase has posted no announcements as of this build. Here is that finding, what a search for outside discussion turned up, and this site's own dated history.
Official word, and what we found elsewhere

GuaBase's own Announcements page was empty at every check during this build, from the first capture on October 21, 2026 through a re-check on October 22, 2026: “No announcements yet.” That is a real, checkable fact about a young service, not a gap in this site's research, and it is why no page here invents a promotion, event, or outage notice that GuaBase has not actually posted.
An empty announcements page is not unusual for a service this new, GuaBase's own policy dates (Terms of Service effective August 1, 2026, Privacy Policy effective February 21, 2026) put its public launch inside the same year as this site's build. What matters for a shopper is less the empty page itself and more what it implies: there is no public record yet of how GuaBase has handled a widescale disruption, a pricing change, or a policy update, because none appears to have happened publicly so far. That absence of a track record is a fact to factor in, not something this site can fill in with a guess.
This page will be the one that changes first if that record starts to exist, a posted maintenance window, a fee change, or a policy update would all show up here with the date it was noticed, rather than being folded silently into other pages after the fact.
What we found when we checked for public chatter
A Reddit search for “guabase” on October 22, 2026 returned no relevant community or thread, the closest matches were unrelated subreddits whose names happen to share letters with the brand. A YouTube search turned up no verified official channel; handles that resemble the brand name either 404 or belong to an unrelated account with no link back to guabase.com anywhere on its own site.
That is reported here as a finding, not filled in with invented reviews. A service this new simply may not have a public conversation yet; if that changes, this page is the one that gets updated, with a date.
Dated entries for every change here

This site tracks its own changes on a dated, per-change basis rather than a single blanket “last updated” claim. The three entries below cover everything that has happened since this site's source material was first assembled, and future entries will be added the same way, one line per change, rather than folded invisibly into existing pages.
This approach is deliberate, and it is the same standard the Choosing a Spreadsheet Site page asks a reader to apply to any reference site, including this one: a specific, dated entry is checkable in a way a vague “periodically updated” claim is not. If a fact on this site turns out to be stale, the fix will show up here with a date, not silently.
What would trigger an entry: a change to GuaBase's published service-fee rate or minimum, a new or removed shipping line, a change to the stated storage window, a resolution of the 1688 support conflict noted on the FAQ and Glossary pages, or GuaBase posting its first real announcement. None of those have happened as of this build; this paragraph exists so a future reader can see exactly what would count as news.
