Comment (by cypherpunks):

 Just got it again recently. That HS was ddosed and not accessible during
 many minutes for me. When I had reloaded the tabs I immediately got this:

 [warn] connection_ap_attach_pending(): Bug: 0x561db4544e70 is no longer in
 circuit_wait. Its current state is waiting for rendezvous desc. Why is it
 on pending_entry_connections? (on Tor 0.3.1.7 )

 The same day from the same HS I got many messages of the form:

 [warn] Query '[scrubbed]' didn't have valid rend desc in cache. Failing.

 May it be HS admins doing some type of attack against their users?
