Last week, we moved wikidata traffic in eqiad (so in practice, all non-European traffic)
from Squid to the new text Varnish cluster. A few issues were found and fixed, and we
haven't seen any new issues for several days.
Today I've done the same for Wikivoyage. Non-European Wikivoyage traffic, served by
our eqiad cluster, is now served by Varnish. Wikivoyage has a bigger portion of normal
users vs. API/bot traffic, so some new issues could surface.
Please let us know if you see any problems on Wikivoyage that might be related to the
Varnish migration; file a Bugzilla ticket or mail me directly.
